Round thermometer mounted outside a window shows a temperature below 0 degrees Fahrenheit. The window has frost and cracks, with snow on the sill. Three thermometers compare temperature scales, showing absolute zero, freezing, and boiling points of water in Celsius, Fahrenheit, and Kelvin, with labeled values for each scale. ahrenheit to Celsius converter interface with pink input box, temperature field set to 0 degrees Fahrenheit, output 0 degrees Celsius, and formula (degrees Fahrenheit minus 32) times 5 divided by 9 equals degrees Celsius. Two world maps compare projected changes in average surface temperature between 2020-2029 and 2090-2099, relative to 1980-1999. The 2020s map shows mostly light yellow and orange shades, indicating moderate warming across most continents. By the 2090s, the map is dominated by dark red and purple, especially in northern latitudes, illustrating much higher temperature increases globally. A color scale at right shows temperature changes in degrees Celsius and Fahrenheit. Three line graphs display trends from 1850 to 2000: global average temperature and sea level both rise, while Northern Hemisphere snow cover declines, illustrating climate change impacts. pure water and temperature A graph plots reduced magnetization versus reduced temperature for a magnet, showing experimental curves for nickel and a nickel-copper alloy, and a theoretical curve for J equals one-half. Magnetization decreases as temperature approaches the critical point. global average surface temperature A vertical temperature scale shows the cryogenic region, highlighted from absolute zero up to about 90 kelvin, with key points where gases like oxygen, nitrogen, hydrogen, and helium liquefy, alongside temperature conversions between kelvin, Celsius, Fahrenheit, and Rankine.

temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). Temperature is not the equivalent of the energy of a thermodynamic system; e.g., a burning match is at a much higher temperature than an iceberg, but the total heat energy contained...
