paragraph_text: Several solid dielectrics are available, including paper, plastic, glass, mica and ceramic materials. Paper was used extensively in older devices and offers relatively high voltage performance. However, it is susceptible to water absorption, and has been largely replaced by plastic film capacitors. Plastics offer better stability and ageing performance, which makes them useful in timer circuits, although they may be limited to low operating temperatures and frequencies. Ceramic capacitors are generally small, cheap and useful for high frequency applications, although their capacitance varies strongly with voltage and they age poorly. They are broadly categorized as class 1 dielectrics, which have predictable variation of capacitance with temperature or class 2 dielectrics, which can operate at higher voltage. Glass and mica capacitors are extremely reliable, stable and tolerant to high temperatures and voltages, but are too expensive for most mainstream applications. Electrolytic capacitors and supercapacitors are used to store small and larger amounts of energy, respectively, ceramic capacitors are often used in resonators, and parasitic capacitance occurs in circuits wherever the simple conductor-insulator-conductor structure is formed unintentionally by the configuration of the circuit layout.

paragraph_text: Mean monthly temperatures range from around 53 F in January to 82 F in July. High temperatures average 64 to 92 °F (18 to 33 °C) throughout the year. High heat indices are common for the summer months in the area, with indices above 110 °F (43.3 °C) possible. The highest temperature recorded was 104 °F (40 °C) on July 11, 1879 and July 28, 1872. It is common for thunderstorms to erupt during a typical summer afternoon. These are caused by the rapid heating of the land relative to the water, combined with extremely high humidity.

paragraph_text: The climate varies regionally. The low-lying Fergana Valley in the southwest is subtropical and extremely hot in summer, with temperatures reaching 40 °C (104 °F) The northern foothills are temperate and the Tian Shan varies from dry continental to polar climate, depending on elevation. In the coldest areas temperatures are sub-zero for around 40 days in winter, and even some desert areas experience constant snowfall in this period. In the lowlands the temperature ranges from around -−6 °C (21 °F) in January to 24 °C (75 °F) in July.

paragraph_text: The atmosphere is severely dry nine months of the year, and average annual snowfall is only 18 inches (46 cm), due to the rain shadow effect. Western passes receive small amounts of fresh snow each year but remain traversible all year round. Low temperatures are prevalent throughout these western regions, where bleak desolation is unrelieved by any vegetation bigger than a low bush, and where wind sweeps unchecked across vast expanses of arid plain. The Indian monsoon exerts some influence on eastern Tibet. Northern Tibet is subject to high temperatures in the summer and intense cold in the winter.

paragraph_text: The Kopet-Dag mountain range is about 25 kilometres (16 mi) to the south, and Ashgabat's northern boundary touches the Kara-Kum desert. Because of this Ashgabat has a cold desert climate (Köppen climate classification: BWk) with hot, dry summers and cool, short winters. The average high temperature in July is 38.3 °C (100.9 °F). Nighttimes in the summer are warm, with an average minimum temperature in July of 23.8 °C (75 °F). The average January high temperature is 8.6 °C (47.5 °F), and the average low temperature is −0.4 °C (31.3 °F). The highest temperature ever recorded in Ashgabat is 47.2 °C (117 °F), recorded in June 2015. A low temperature of −24.1 °C (−11 °F) was recorded in January 1969. Snow is infrequent in the area. Annual precipitation is only 201 millimetres (7.91 in); March and April are the wettest months, and summer drought, from late June to September, is virtually absolute.

paragraph_text: Daily maximum temperatures are normally in the mid to low 20s (° C) over most of the country. They are higher in northern, eastern and interior part of the country; Hastings is the warmest city on average with 25.5 ° C followed by Gisborne with 24.9 ° C and Napier with 24.5 ° C. Eastern parts of the South Island are highly susceptible to the norwester, a Fohn wind which can result in temperatures going into the high 30s and even the low 40s. Rangiora in Canterbury holds the record maximum of 42.4 ° C recorded in 1973, with Christchurch recording 41.6 ° C in that same year. More recently, Timaru reached 41.3 ° C on Waitangi Day in 2011. Due to these winds, the cooler southern cities of Dunedin and Invercargill have higher all - time record temperatures than places further north such as Wellington, Auckland and Whangarei.

paragraph_text: The Victorian Alps in the northeast are the coldest part of Victoria. The Alps are part of the Great Dividing Range mountain system extending east-west through the centre of Victoria. Average temperatures are less than 9 °C (48 °F) in winter and below 0 °C (32 °F) in the highest parts of the ranges. The state's lowest minimum temperature of −11.7 °C (10.9 °F) was recorded at Omeo on 13 June 1965, and again at Falls Creek on 3 July 1970. Temperature extremes for the state are listed in the table below:

paragraph_text: Rowe Point is a sharp, low ice-free point at the northeast extremity of Ivanov Beach on the southeast coast of Barclay Bay in western Livingston Island in the South Shetland Islands, Antarctica.

paragraph_text: The climate of Florida is tempered somewhat by the fact that no part of the state is distant from the ocean. North of Lake Okeechobee, the prevalent climate is humid subtropical (Köppen: Cfa), while areas south of the lake (including the Florida Keys) have a true tropical climate (Köppen: Aw). Mean high temperatures for late July are primarily in the low 90s Fahrenheit (32–34 °C). Mean low temperatures for early to mid January range from the low 40s Fahrenheit (4–7 °C) in northern Florida to above 60 °F (16 °C) from Miami on southward. With an average daily temperature of 70.7 °F (21.5 °C), it is the warmest state in the country.

paragraph_text: The temperature range for process annealing ranges from 260 °C (500 °F) to 760 °C (1400 °F), depending on the alloy in question. This process is mainly suited for low-carbon steel. The material is heated up to a temperature just below the lower critical temperature of steel. Cold-worked steel normally tends to possess increased hardness and decreased ductility, making it difficult to work. Process annealing tends to improve these characteristics. This is mainly carried out on cold-rolled steel like wire-drawn steel, centrifugally cast ductile iron pipe etc.

paragraph_text: Liquid metal consists of alloys with very low melting points which form a eutectic that is liquid at room temperature. The standard metal used to be mercury, but gallium - based alloys, which are lower both in their vapor pressure at room temperature and toxicity, are being used as a replacement in various applications.

A decade or two may pass between readings of 100 °F (38 °C) or higher, which last occurred July 17, 2012. The average window for freezing temperatures is October 20 thru April 22, allowing a growing season of 180 days.

paragraph_text: Summers are typically warm and humid with a July daily average of 75.6 °F (24.2 °C). During this time, the city gets a sea breeze off the ocean that often makes daytime temperatures much cooler than inland areas, making Atlantic City a prime place for beating the summer heat from June through September. Average highs even just a few miles west of Atlantic City exceed 85 °F (29 °C) in July. Near the coast, temperatures reach or exceed 90 °F (32 °C) on an average of only 6.8 days a year, but this reaches 21 days at nearby Atlantic City Int'l.[a] Winters are cool, with January averaging 35.5 °F (2 °C). Spring and autumn are erratic, although they are usually mild with low humidity. The average window for freezing temperatures is November 20 to March 25, allowing a growing season of 239 days. Extreme temperatures range from −9 °F (−23 °C) on February 9, 1934 to 104 °F (40 °C) on August 7, 1918.[b]

paragraph_text: Uranium metal heated to 250 to 300 °C (482 to 572 °F) reacts with hydrogen to form uranium hydride. Even higher temperatures will reversibly remove the hydrogen. This property makes uranium hydrides convenient starting materials to create reactive uranium powder along with various uranium carbide, nitride, and halide compounds. Two crystal modifications of uranium hydride exist: an α form that is obtained at low temperatures and a β form that is created when the formation temperature is above 250 °C.

paragraph_text: The Crystal Hills are a low mountain range in the Mojave Desert, in extreme southwestern section of Death Valley National Park, California.

paragraph_text: Most of Germany has a temperate seasonal climate dominated by humid westerly winds. The country is situated in between the oceanic Western European and the continental Eastern European climate. The climate is moderated by the North Atlantic Drift, the northern extension of the Gulf Stream. This warmer water affects the areas bordering the North Sea; consequently in the northwest and the north the climate is oceanic. Germany gets an average of 789 mm (31 in) of precipitation per year; there is no consistent dry season. Winters are cool and summers tend to be warm: temperatures can exceed 30 °C (86 °F).The east has a more continental climate: winters can be very cold and summers very warm, and longer dry periods can occur. Central and southern Germany are transition regions which vary from moderately oceanic to continental. In addition to the maritime and continental climates that predominate over most of the country, the Alpine regions in the extreme south and, to a lesser degree, some areas of the Central German Uplands have a mountain climate, with lower temperatures and more precipitation.Though the German climate is rarely extreme, there are occasional spikes of cold or heat. Winter temperatures can sometimes drop to two-digit negative temperatures for a few days in a row. Conversely, summer can see periods of very high temperatures for a week or two. The recorded extremes are a maximum of 40.3 °C (104.5 °F) (July 2015, in Kitzingen), and a minimum of −37.8 °C (−36.0 °F) (February 1929, in Pfaffenhofen an der Ilm).

paragraph_text: Extreme temperatures range from − 12 ° F (− 24 ° C), recorded on December 8, 1972, to 108 ° F (42 ° C) on August 9, 1981.

paragraph_text: January is the coldest month with an average temperature of 29.2 ° F (− 1.6 ° C). Salt Lake City's record low maximum temperature is 2 ° F (− 16.7 ° C), set on December 22, 1990, during an extended period of frigid Arctic air, and its overall record low temperature is − 30 ° F (− 34.4 ° C), set on February 9, 1933 during a historic cold air surge from the north. During spring, temperatures warm steadily and rapidly. Wintry weather is usually last experienced by early - to - mid April. Summery weather first arrives in early to mid May; the earliest 90 ° F (32.2 ° C) temperature on record was on May 2. Major cold fronts typically stop arriving in late May or early June.
