What is Absolute temperature?
''' Absolute temperature''', also called '''thermodynamic temperature''', is the [[temperature]] of an [[object]] on a scale where [[0|zero]] is taken as [[absolute zero]]. Absolute temperature scales are ''[[Kelvin]]'' and ''[[Rankine]]''. Absolute zero is the temperature at which a system is in the state of lowest possible (minimum) energy. As [[molecule]]s approach this temperature, their movements continue to slow down. The [[kinetic energy]] of the molecules becomes negligible. However, the molecules will [[Zero-point energy|never stop moving nor have no energy]]. It is the lowest temperature a gas [[thermometer]] can measure. No electronic [[device]]s work at this temperature. No living thing can survive in this temperature. ==Examples== Common temperatures in the absolute scale are: *0&nbsp;°C ([[freezing point]] of [[water]]) = 273.15 K *25&nbsp;°C (room temperature) = 298.15 K *100&nbsp;°C ([[boiling point]] of water) = 373.15 K *0 K (absolute zero) = -273.15 °C *233.15 K (equal measures in Celsius and Fahrenheit)= -40 [[Celsius]] * Triple point of water= 273.16K (equal measure in Celsius) 0.01°C. ==Conversion== To convert from the Celsius scale into the absolute temperature, you add 273.15 and change °C to K. To get a temperature on the absolute scale to the Celsius scale, subtract 273.15 and change K to °C. This is normally used in the science world. Kelvin is used globally as a part of the [[International System of Units]]. It is one of the 7 base units of the system. The value of absolute temperature is 0 K. * Celsius to Kelvin: K = C + 273.15 * Kelvin to Celsius: C = K - 273.15 * Fahrenheit to Rankine: R = F + 459.67 * Rankine to Fahrenheit: F = R - 459.67 {{sci-stub}} {{authority control}} [[Category:Temperature]]
