Water heating is a thermodynamic process using an energy source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking, cleaning and bathing, and space heating. In industry both hot water and water heated to steam have many uses.
The most common energy sources for heating water are fossil fuels: natural gas, liquefied petroleum gas, oil or sometimes solid fuels (coal or firewood. These fuels may be consumed directly or by the use of electricity (which may derive from any of the above fuels or from nuclear or renewable sources). Alternative energy such as solar energy, heat pumps, hot water heat recycling, and sometimes geothermal power, may also be used as available, usually in combination with gas, oil or electricity.
Solar collectors for solar powered water heaters are installed outside dwellings, typically on the roof or nearby. Nearly all models are the direct-gain type. They consist of flat panels in which water circulates.
In countries like Iceland and New Zealand, and other volcanic regions, water heating may be done using geothermal power, rather than combustion.

Room temperature
Room temperature does not have an exact scientific definition. It means a temperature that is normal in rooms used by human beings.
A comfortable room temperature depends on individual needs and other factors. According to the West Midlands Public Health Observatory (UK), is the recommended living room temperature, and is a good bedroom temperature.
However, in hotter countries such as those near the equator room temperature can be as high as .
Room Temperature is the temperature that is comfortable and normal to be in.
For scientific work, room temperature is taken to be in the range with an average of . Scientists use kelvins (K) for temperature. The Rankine (°R) unit is no longer used.
The progress and results of many scientific and industrial processes can sometimes depend on the temperature of the surroundings of the equipment. For example, a measurement of the charge of the electron does not depend upon the temperature of the test equipment. In this case, if scientists mention temperature at all, they usually only mention "room temperature", which means that what is being measured has not been cooled or heated.
Kraftwerk
Kraftwerk is a electronic band from Germany that became famous in the late 1970s and 1980s for making electronic music. They used synthesizers and sequencers to make the rhythms and melodies in the song.
Kraftwerk made electronic music many years before other bands knew it would be popular. They paved the way for the MIDI and digital styles of music to become popular in the 1990s. Many of the sounds from songs such as "Computer Love", "The Robots", and "Trans Europe Express" can be heard sampled by a variety of bands on their current releases. Recently, some of Kraftwerk's original recording equipment was sold on eBay for astonishing amounts. Kraftwerk continues to have a faithful following. The band's name is German for power station.
Cricket ball
A cricket ball is a hard, solid ball used to play cricket. In men's cricket the ball must weigh between 5.5 and 5.75 ounces (137.5 and 143.8 g) and measure between and 9 inches (220 and 225 millimetres) in circumference.
A cricket ball is usually red, white or pink depending upon the game and has a seam over it.
Baptist
Baptist is a word describing a tradition within Christianity and may also refer to individuals belonging to a Baptist church or a Baptist denomination. The tradition takes its name from the belief that followers of Jesus Christ should be placed in water to show their faith. Baptists do not practice infant baptism.
In 1639, Roger Williams began a Baptist church in Providence, Rhode Island and John Clarke began a Baptist church in Newport, Rhode Island. It is not clear which church opened first. Records for both churches are missing information.
Baptist churches do not have a central principal authority. Therefore, beliefs are not the same from one Baptist church to another, mainly beliefs that may be considered minor. However, on major issues, most are held in common among almost all Baptist churches.
Baptists share so-called "orthodox" Christian beliefs with most other moderate or conservative Christian denominations. Some of them are beliefs about one God; Jesus' death, burial, and bodily resurrection; the Trinity (the divinity of Jesus and the Holy Spirit, together with God the Father); the need for salvation; grace; and evangelism and missions.
There are over 90 million Baptists in the world in nearly 300,000 churches. There are about 47 million members in the United States. Other large populations of Baptists also exist in Asia, Africa and Latin America. There are 2.4 million Baptists in India, 2.3 million in Nigeria, 1.9 million in the Democratic Republic of the Congo, and 1.5 million in Brazil.
In a poll in the 1990s, about 20% of Americans said they are Baptist.
Many people outside the community see them as Protestant, but some baptists do not. In their view, Baptists have existed separately since early church days. Those holding this view believe that Baptists have never been a part of the Roman Catholic Church, and that Baptists are not "protesting" against Catholicism.
They also point out that Baptists have no connections with the Reformationists like Luther, Calvin, or Zwingli. Other Baptists accept the "Protestant" label as a category for churches who have similar religious views of "sola scriptura, sola fide," the priesthood of all believers and other positions that Luther or Calvin had in contrast to the Roman Catholic Church in the 1500s.
The tag: "denomination", is rejected by some because of the autonomous system used by Baptist churches for control. Being a denomination is viewed by them as having a hierarchy instead of the Roman Catholic Church. Another reason for the rejection of the tag is the influence of the Restoration period on Baptist churches, which tore down denominational barriers. Other Baptists accept the tag. They feel that it does not lie or have any bad meanings. It is just used as a synonym for a Christian or religious group with common beliefs.
The tag: "Evangelical", is rejected by some fundamentalist Baptists who think that the term is not 'fundamentalist' enough. It is also rejected by some liberal Baptists who think that the term is too conservative. It is accepted by moderate Baptists believing in the revival in the United States in the 1700s called the First Great Awakening. Some Evangelicals also reject the tag: fundamentalist, because they think that it is too extreme.
Techno
Techno is a form of electronic dance music that became popular in Frankfurt, Germany during the early 1980s. It was influenced by synthpop, house music, funk, post-disco and futuristic fiction ideas that were important during the end of the Cold War in the United States at that time. Juan Atkins is generally thought to be the founder of Detroit Techno music. Detroit Techno first became successful locally and then became popular around the world in the 1990s.
The word "techno" comes from "technology". Fans of Techno music are careful in their use of the word. They are careful not to confuse it with other types of music that are similar but different (for example house, trance, hardcore). At the same time, the word "techno" is commonly used when talking about all forms of electronic music and dance music, especially in Europe, the Americas and Australia. Despite the common usage of the term to refer to all electronic dance in general, techno is a specific genre with its own, distinguishable sound. By nature, techno tends to be highly repetitive, instrumentally-oriented music which follows a regular four-on-the-floor beat. The genre places a strong emphasis on rhythm, and techno tends to have a very beat-based sound.
