In this task, you are given a context, a subject, a relation, and many options. Based on the context, from the options select the object entity that has the given relation with the subject. Answer with text (not indexes).

Example Input: Context: Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf., South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil)., Power metal is a subgenre of heavy metal combining characteristics of traditional metal with speed metal, often within symphonic context. Generally, power metal is characterized by a more uplifting sound, instead of the heaviness and dissonance prevalent in styles such as doom metal and death metal. Power metal bands usually have anthem-like songs with fantasy-based subject matter and strong choruses, thus creating a theatrical, dramatic and emotionally "powerful" sound. The term was first used in the middle of the 1980s and refers to two different but related styles: the first pioneered and largely practiced in North America with a harder sound similar to speed metal, and a later more widespread and popular style based in Europe (especially Scandinavia, Germany, Greece and Italy), South America (especially Brazil and Argentina) and Japan, with a lighter, more melodic sound and frequent use of keyboards., MPEG-1 and/or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players and computing devices., Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking, deep growling vocals and screams, aggressive, powerful drumming featuring double kick or blast beat techniques, minor keys or atonality, abrupt tempo, key, and time signature changes and chromatic chord progressions. The lyrical themes of death metal may invoke slasher film-stylized violence, religion (sometimes Satanism), occultism, Lovecraftian horror, nature, mysticism, mythology, philosophy, science fiction, and politics, and they may describe extreme acts, including mutilation, dissection, torture, rape, cannibalism, and necrophilia., A book is a set of written, printed, illustrated, or blank sheets, made of paper, parchment, or other materials, fastened together to hinge at one side, with text and/or images printed in ink. A single sheet within a book is a leaf, and each side of a leaf is a page. A set of text-filled or illustrated pages produced in electronic format is known as an electronic book, or e-book. , Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, then from 1948 as vinyl LP records played at  rpm. Vinyl LPs are still issued, though in the 21st century album sales have mostly focused on compact disc (CD) and MP3 formats. The audio cassette was a format used from the late 1970s through to the 1990s alongside vinyl., North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea., Greece (' ), officially the Hellenic Republic (Greek: ' ), historically also known as Hellas ("" ), is a country in southeastern Europe. 
Greece's population is approximately 10.955 million as of 2015. Athens is the nation's capital and largest city, followed by Thessaloniki., Compact disc (CD) is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. Audio CD players have been commercially available since October 1982, when the first commercially available CD player was released in Japan., Doom metal is an extreme style of heavy metal music that typically uses slower tempos, low-tuned guitars and a much "thicker" or "heavier" sound than other metal genres. Both the music and the lyrics intend to evoke a sense of despair, dread, and impending doom. The genre is strongly influenced by the early work of Black Sabbath, who formed a prototype for doom metal with songs such as "Black Sabbath", "Children of the Grave", "Electric Funeral" and "Into the Void". During the first half of the 1980s, a number of bands from England (Pagan Altar, Witchfinder General), the United States (Pentagram, Saint Vitus, Trouble) and Sweden (Candlemass, Count Raven) defined doom metal as a distinct genre., Speed metal is an extreme subgenre of heavy metal music that originated in the late 1970s from new wave of British heavy metal (NWOBHM) roots. It is described by AllMusic as "extremely fast, abrasive, and technically demanding" music., The LP (from "long playing" or "long play") is an analog sound storage medium, a vinyl record format characterized by a speed of rpm, a 12 or 10 inch (30 or 25 cm) diameter, and use of the "microgroove" groove specification. Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it has remained the standard format for vinyl albums., Fantasy is a fiction genre set in an imaginary universe, often but not always without any locations, events, or people from the real world. Most fantasy uses magic or other supernatural elements as a main plot element, theme, or setting. Magic and magical creatures are common in many of these imaginary worlds. Fantasy is generally distinguished from the genres of science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there is a great deal of overlap between the three, all of which are subgenres of speculative fiction., Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of , Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into twenty-three provinces (singular "provincia") and one autonomous city ("ciudad autónoma"), Buenos Aires, which is the federal capital of the nation as decided by Congress.
The provinces and the capital have their own constitutions, but exist under a federal system., Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection., Wyrd is the second full - length album by Italian folk / power metal band Elvenking ., Subject: wyrd , Relation: genre, Options: (A) album (B) atonality (C) book (D) country (E) death metal (F) debate (G) doom metal (H) fantasy (I) genre (J) heavy metal (K) heavy metal music (L) music (M) nature (N) play (O) power metal (P) religion (Q) romance (R) science (S) science fiction (T) speculative (U) speed metal (V) supernatural (W) universe (X) variety (Y) video (Z) western ([) wildlife

Example Input: Context: A film score (also sometimes called background score, background music, movie soundtrack, film music or incidental music) is original music written specifically to accompany a film. The score forms part of the film's soundtrack, which also usually includes dialogue and sound effects, and comprises a number of orchestral, instrumental, or choral pieces called cues, which are timed to begin and end at specific points during the film in order to enhance the dramatic narrative and the emotional impact of the scene in question. Scores are written by one or more composers, under the guidance of, or in collaboration with, the film's director or producer and are then usually performed by an ensemble of musicians  most often comprising an orchestra or band, instrumental soloists, and choir or vocalists  and recorded by a sound engineer., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., Ian Stuart Donaldson (11 August 1957  24 September 1993), also known as Ian Stuart, was a white supremacist musician from Poulton-le-Fylde, Lancashire. He was best known as the frontman of Skrewdriver, a British punk rock band which he rebranded as a white power rock band. He raised money through white power concerts with his Blood and Honour network., It's Too Late to Stop Now is a live album by Northern Irish singer-songwriter Van Morrison, released in 1974 (see 1974 in music). Frequently named as one of the best live albums ever recorded, "It's Too Late to Stop Now" was recorded during what has often been said to be Morrison's greatest phase as a live performer., Northern Ireland (; Ulster Scots: "") is a top-level constituent unit of the United Kingdom in the northeast of Ireland. It is variously described as a country, province, region, or "part" of the United Kingdom, amongst other terms. Northern Ireland shares a border to the south and west with the Republic of Ireland. In 2011, its population was 1,810,863, constituting about 30% of the island's total population and about 3% of the UK's population. Established by the Northern Ireland Act 1998 as part of the Good Friday Agreement, the Northern Ireland Assembly holds responsibility for a range of devolved policy matters, while other areas are reserved for the British government. Northern Ireland co-operates with the Republic of Ireland in some areas, and the Agreement granted the Republic the ability to "put forward views and proposals" with "determined efforts to resolve disagreements between the two governments"., Nicholas Edward "Nick" Cave (born 22 September 1957) is an Australian musician, singer-songwriter, author, screenwriter, composer and occasional film actor, best known as the frontman of Nick Cave and the Bad Seeds. Referred to as rock music's "Prince of Darkness", Cave's music is generally characterised by emotional intensity, a wide variety of influences, and lyrical obsessions with death, religion, love and violence. "NME" called him "the grand lord of gothic lushness"., Belfast is the capital and largest city of Northern Ireland, the second largest on the island of Ireland, and the heart of the tenth largest Primary Urban Area in the United Kingdom. On the River Lagan, it had a population of 286,000 at the 2011 census and 333,871 after the 2015 council reform. Belfast was granted city status in 1888., Shawn Colvin (born January 10, 1956) is an American country folk and americana singer-songwriter and musician widely known for her Grammy-winning 1997 single "Sunny Came Home"., Stephen Fain "Steve" Earle (born January 17, 1955) is an American rock, country and folk singer-songwriter, record producer, author and actor. Earle began his career as a songwriter in Nashville and released his first EP in 1982. His breakthrough album was the 1986 album "Guitar Town". Since then Earle has released 15 other studio albums and received three Grammy awards. His songs have been recorded by Johnny Cash, Waylon Jennings, Travis Tritt, Vince Gill, Patty Loveless, Shawn Colvin, Ian Stuart Donaldson and Emmylou Harris. He has appeared in film and television, and has written a novel, a play, and a book of short stories., Mark Freuder Knopfler, (born 12 August 1949) is a Scottish singer, songwriter, guitarist, record producer and film score composer. He is best known as the lead guitarist, lead singer and songwriter for the rock band Dire Straits, which he co-founded with his younger brother, David Knopfler, in 1977., David Knopfler (born 27 December 1952) is a British guitarist, pianist, record producer and singer-songwriter. He is also a poet and book writer., A Primary Urban Area (PUA) is an area defined by the Department for Communities and Local Government in the United Kingdom as a statistical tool for analysing the major cities of England, originating as part of their "State of the English Cities" report and database., Vincent Grant "Vince" Gill (born April 12, 1957) is an American country singer, songwriter and multi-instrumentalist. He has achieved commercial success and fame both as frontman to the country rock band Pure Prairie League in the 1970s and as a solo artist beginning in 1983, where his talents as a vocalist and musician have placed him in high demand as a guest vocalist and a duet partner., Ireland, also described as the Republic of Ireland ('), is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the eastern part of the island, and whose metropolitan area is home to around a third of the country's 4.75 million inhabitants. The state shares its only land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the ', consists of a lower house, ', an upper house, ', and an elected President (') who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the ' (Prime Minister, literally 'Chief', a title not used in English), who is elected by the Dáil and appointed by the President, and appoints other government ministers., Patty Loveless (born Patty Lee Ramey; January 4, 1957) is an American country music singer., A musician (or instrumentalist) is a person who plays a musical instrument or is musically talented. Anyone who composes, conducts, or performs music may also be referred to as a musician. , Singer-songwriters are musicians who write, compose, and perform their own musical material, including lyrics and melodies., Guitar Town is the debut album from singer-songwriter Steve Earle, released on March 5, 1986. It topped the "Billboard" country album charts, and the title song reached #7 on the country singles charts. Earle was also nominated for two 1987 Grammy Awards, Best Male Country Vocalist and Best Country Song, for the title track., Sir George Ivan Morrison, OBE (born 31 August 1945), known as Van Morrison, is a Northern Irish singer and songwriter with a reputation for being at once stubborn, idiosyncratic, and sublime. His studio albums "Astral Weeks" and "Moondance", and the live album "It's Too Late to Stop Now", are acclaimed as among the greatest recorded. In 2016, he was knighted for his musical achievements and his services to tourism and charitable causes in Northern Ireland., Moondance is the third studio album by Northern Irish singer-songwriter Van Morrison. After recording his commercially unsuccessful 1968 album "Astral Weeks", Morrison moved with his wife to an artistic hamlet in upstate New York and began writing songs for "Moondance". There, he met the musicians he would record the album with at New York City's A & R Studios in 1969., The Popes are a band originally formed by Shane MacGowan (of the Pogues) and Paul "Mad Dog" McGuinness, who play a blend of rock, Irish folk and Americana., Lyrics are words that make up a song usually consisting of verses and choruses. The writer of lyrics is a lyricist. The words to an extended musical composition such as an opera are, however, usually known as a "libretto" and their writer, as a "librettist". The meaning of lyrics can either be explicit or implicit. Some lyrics are abstract, almost unintelligible, and, in such cases, their explication emphasizes form, articulation, meter, and symmetry of expression. Rappers can also create lyrics with a variation of rhyming words or words that create and tell a story or song., Astral Weeks is the second studio album by Northern Irish singer-songwriter Van Morrison. It was recorded at Century Sound Studios in New York City during three sessions in September and October 1968, although most participants and biographers agree that the eight songs were culled from the first and last early evening sessions. Except for John Payne, Morrison and the assembled jazz musicians had not played together before and the recordings commenced without rehearsals or lead sheets handed out., John Graham Mellor (21 August 1952  22 December 2002), known by his stage name Joe Strummer, was a British musician, singer, actor and songwriter who was the co-founder, lyricist, rhythm guitarist and lead vocalist of the Clash, a punk rock band that was formed in 1976 as part of the original wave of British punk. Their music also incorporated elements of reggae, ska, dub, funk, rap, and rockabilly. The Clash were one of the most prominent of the emerging bands in the UK punk rock scene, with their second album, "Give 'Em Enough Rope" (1978) reaching number 2 on the UK charts. Soon after, they began achieving success in the US, starting with "London Calling" (1979), and peaking with 1982's "Combat Rock", reaching number 7 on the US charts and being certified 2× platinum there. The Clash's politicised lyrics, musical experimentation, and rebellious attitude had a far-reaching influence on rock, and alternative rock in particular., Bap Kennedy ( born Martin Christopher Kennedy ; 17 June 1962 ) is a singer - songwriter from Belfast , Northern Ireland . He is noted for his collaborations with Steve Earle , Van Morrison , Shane MacGowan and Mark Knopfler , as well as for writing the song `` Moonlight Kiss '' which was on the soundtrack for the film Serendipity ( starring John Cusack and Kate Beckinsale ) . Kennedy was in a successful band , Energy Orchard for many years and has also recorded a number of well - received solo albums including Domestic Blues , The Big Picture , The Sailor 's Revenge and Let 's Start Again . During his solo career , Kennedy has performed , written and recorded songs with artists such as Steve Earle ( on Domestic Blues ) , Van Morrison ( on The Big Picture ) and Mark Knopfler ( on The Sailor 's Revenge ) . Following the releases of The Big Picture and The Sailor 's Revenge , he toured the USA and Europe with Mark Knopfler of Dire Straits , who also produced Kennedy 's 2012 album The Sailor 's Revenge ., Waylon Arnold Jennings (pronounced ; June 15, 1937  February 13, 2002) was an American singer, songwriter, musician, and actor. Jennings began playing guitar at eight and began performing at 14 on KVOW radio. His first band was The Texas Longhorns. Jennings worked as a DJ on KVOW, KDAV, KYTI, and KLLL. In 1958, Buddy Holly arranged Jennings's first recording session, of "Jole Blon" and "When Sin Stops (Love Begins)". Holly hired him to play bass. In Clear Lake, Iowa, Jennings gave up his seat on the ill-fated flight that crashed and killed Holly, J. P. Richardson, Ritchie Valens, and pilot Roger Peterson., Dire Straits were a British rock band that formed in Deptford, London, in 1977 by Mark Knopfler (lead vocals and lead guitar), his younger brother David Knopfler (rhythm guitar and backing vocals), John Illsley (bass guitar and backing vocals), and Pick Withers (drums and percussion). Dire Straits' sound drew from a variety of musical influences, including jazz, folk, and blues, and came closest to beat music within the context of rock and roll. Despite the prominence of punk rock during the band's early years, their stripped-down sound contrasted with punk, demonstrating a more "rootsy" influence that emerged from pub rock. Many of Dire Straits' compositions were melancholic., Johnny Cash (born J. R. Cash; February 26, 1932  September 12, 2003) was an American singer-songwriter, guitarist, actor, and author. He was widely considered one of the most influential musicians of the 20th century and one of the best-selling music artists of all time, having sold more than 90 million records worldwide. Although primarily remembered as a country music icon, his genre-spanning songs and sound embraced rock and roll, rockabilly, blues, folk, and gospel. This crossover appeal won Cash the rare honor of multiple inductions in the Country Music, Rock and Roll, and Gospel Music Halls of Fame., Shane Patrick Lysaght MacGowan (born 25 December 1957) is an Irish-British musician and singer, best known as the lead singer and songwriter of Celtic trad punk band the Pogues. He was also a member of the Nipple Erectors and Shane MacGowan and the Popes, as well as producing his own solo material and working on collaborations with artists such as Kirsty MacColl, Joe Strummer, Nick Cave, Steve Earle, and Sinéad O'Connor., A Grammy Award (originally called Gramophone Award), or Grammy, is an honor awarded by The Recording Academy to recognize outstanding achievement in the mainly English-language music industry. The annual presentation ceremony features performances by prominent artists, and the presentation of those awards that have a more popular interest. It shares recognition of the music industry as that of the other performance awards such as the Emmy Awards (television), the Tony Awards (stage performance), and the Academy Awards (motion pictures)., Sinéad Marie Bernadette OConnor (born 8 December 1966) is an Irish singer-songwriter who rose to fame in the late 1980s with her debut album "The Lion and the Cobra". OConnor achieved worldwide success in 1990 with a new arrangement of Princes song "Nothing Compares 2 U"., James Travis Tritt (born February 9, 1963) is an American country music singer, songwriter, and actor. He signed to Warner Bros. Records in 1989, releasing seven studio albums and a greatest hits package for the label between then and 1999.

Example Input: Context: Waste heat is by necessity produced both by machines that do work and in other processes that use energy, for example in a refrigerator warming the room air or a combustion engine releasing heat into the environment. The need for many systems to reject heat as a by-product of their operation is fundamental to the laws of thermodynamics. Waste heat has lower utility (or in thermodynamics lexicon a lower exergy or higher entropy) than the original energy source. Sources of waste heat include all manner of human activities, natural systems, and all organisms. Rejection of unneeded cold (as from a heat pump) is also a form of waste heat (i.e. the medium has heat, but at a lower temperature than is considered warm)., Vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapor pressure at normal temperatures is often referred to as "volatile". The pressure exhibited by vapor present above a liquid surface is known as vapor pressure. As the temperature of a liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure., The Organic Rankine cycle ( ORC ) is named for its use of an organic , high molecular mass fluid with a liquid - vapor phase change , or boiling point , occurring at a lower temperature than the water - steam phase change . The fluid allows Rankine cycle heat recovery from lower temperature sources such as biomass combustion , industrial waste heat , geothermal heat , solar ponds etc. The low - temperature heat is converted into useful work , that can itself be converted into electricity . A prototype was first developed and exhibited in 1961 by solar engineers Harry Zvi Tabor and Lucien Bronicki . Similar naphtha engines though , developed for other reasons , had been in use since the 1890s ., William John Macquorn Rankine, (5 July 1820  24 December 1872) was a Scottish mechanical engineer who also contributed to civil engineering, physics and mathematics. He was a founding contributor, with Rudolf Clausius and William Thomson (Lord Kelvin), to the science of thermodynamics, particularly focusing on the first of the three thermodynamic laws., The Rankine cycle is a model that is used to predict the performance of steam turbine systems. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work. The heat is supplied externally to a closed loop, which usually uses water as the working fluid. It is named after William John Macquorn Rankine, a Scottish polymath and Glasgow University professor., A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Water is, by far, the most common liquid on Earth. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena., The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor., The four laws of thermodynamics define fundamental physical quantities (temperature, energy, and entropy) that characterize thermodynamic systems at thermal equilibrium. The laws describe how these quantities behave under various circumstances, and forbid certain phenomena (such as perpetual motion)., A polymath ("", "having learned much") is a person whose expertise spans a significant number of different subject areas; such a person is known to draw on complex bodies of knowledge to solve specific problems. , A machine is a tool containing one or more parts that uses energy to perform an intended action. Machines are usually powered by chemical, thermal, or electrical means, and are often motorized. Historically, a power tool also required moving parts to classify as a machine. However, the advent of electronics has led to the development of power tools without moving parts that are considered machines., Pressure (symbol: "p" or "P") is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled "gage" pressure) is the pressure relative to the ambient pressure., A turbine (from the Latin "turbo", a vortex, related to the Greek , "tyrb", meaning "turbulence") is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator or producing thrust, as in the case of jet engines. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels., In physics, energy is the property that must be transferred to an object in order to perform work on  or to heat  the object, and can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton., In physics a vapor (American) or vapour (British) is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature. A vapor is different from an aerosol. An aerosol is a suspension of tiny particles of liquid, solid, or both within a gas., In statistical thermodynamics, entropy (usual symbol ) (Greek:,  + ) is a measure of the number of microscopic configurations that a thermodynamic system can have when in a state as specified by certain macroscopic variables. Specifically, assuming that each of the microscopic configurations is equally probable, the entropy of the system is the natural logarithm of that number of configurations, multiplied by the Boltzmann constant (which provides consistency with the original thermodynamic concept of entropy discussed below, and gives entropy the dimension of energy divided by temperature). Formally,, In thermodynamics, the exergy (in older usage, available work and/or availability) of a system is the maximum useful work possible during a process that brings the system into equilibrium with a heat reservoir. When the surroundings are the reservoir, exergy is the potential of a system to cause a change as it achieves equilibrium with its environment. Exergy is the energy that is available to be used. After the system and surroundings reach equilibrium, the exergy is zero. Determining exergy was also the first goal of thermodynamics. The term "exergy" was coined in 1956 by Zoran Rant (19041972) by using the Greek "ex" and "ergon" meaning "from work", but the concept was developed by J. Willard Gibbs in 1873., In thermodynamics, a heat engine is a system that converts heat or thermal energyand chemical energyto mechanical energy, which can then be used to do mechanical work. It does this by bringing a working substance from a higher state temperature to a lower state temperature. A heat "source" generates thermal energy that brings the working substance to the high temperature state. The working substance generates work in the "working body" of the engine while transferring heat to the colder "sink" until it reaches a low temperature state. During this process some of the thermal energy is converted into work by exploiting the properties of the working substance. The working substance can be any system with a non-zero heat capacity, but it usually is a gas or liquid. During this process, a lot of heat is lost to the surroundings, i.e. it cannot be used., A thermodynamic cycle consists of a linked sequence of thermodynamic processes that involve transfer of heat and work into and out of the system, while varying pressure, temperature, and other state variables within the system, and that eventually returns the system to its initial state. In the process of passing through a cycle, the working fluid (system) may convert heat from a warm source into useful work, and dispose of the remaining heat to a cold sink, thereby acting as a heat engine. Conversely, the cycle may be reversed and use work to move heat from a cold source and transfer it to a warm sink thereby acting as a heat pump., A working fluid is a pressurized gas or liquid that actuates a machine. Examples include steam in a steam engine, air in a hot air engine and hydraulic fluid in a hydraulic motor or hydraulic cylinder. More generally, in a thermodynamic system, the working fluid is a liquid or gas that absorbs or transmits energy., In physics, heat is that amount of energy flowing from one body to another spontaneously due to their temperature difference, or by any means other than through work or the transfer of matter. The transfer can be by contact between the source and the destination body, as in conduction; or by radiation between remote bodies; or by conduction and radiation through a thick solid wall; or by way of an intermediate fluid body, as in convective circulation; or by a combination of these. , Steam is water in the gas phase, which is formed when water boils. Steam is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as this water vapour condenses. At lower pressures, such as in the upper atmosphere or at the top of high mountains, water boils at a lower temperature than the nominal at standard pressure. If heated further it becomes superheated steam., Subject: organic rankine cycle, Relation: instance_of, Options: (A) area (B) assembly (C) chemical (D) concept (E) constant (F) container (G) cycle (H) december (I) destination (J) device (K) drum (L) electronics (M) engine (N) engineering (O) environment (P) fluid (Q) force (R) four (S) gas (T) high mountains (U) july (V) learned (W) liquid (X) machine (Y) mathematics (Z) metre ([) model (\) motion (]) natural logarithm (^) number (_) object (`) person (a) phase (b) physics (c) point (d) process (e) product (f) property (g) room (h) scottish (i) space (j) standard (k) state (l) steam engine (m) symbol (n) system (o) temperature (p) term (q) thermodynamic cycle (r) three (s) turbine (t) unit of energy (u) vapor (v) volume (w) wall (x) water (y) work
