===About Absolute Temperature===
*[[Absolute Temperature|Absolute temperature]] uses the [[Kelvin]] scale, where 0 [[Kelvin|K]] represents *[[Absolute Zero|absolute zero]].
*[[Absolute Zero|Absolute zero]] is the point where a [[system]] has minimum [[Internal Energy|internal energy]].
*The [[Kelvin]] scale is an absolute thermodynamic [[temperature]] scale.
*[[Absolute Temperature|Absolute temperature]] differs from [[Degrees Celsius|Celsius]] and [[Fahrenheit]] scales in that it starts at [[Absolute Zero|absolute zero]].
*[[Absolute Temperature|Absolute temperature]] is crucial for calculations in thermodynamics and statistical mechanics.
*At [[Absolute Zero|absolute zero]], entropy of a perfect crystal is zero according to the third law of thermodynamics.
===Examples===
*The [[temperature]] of [[liquid]] nitrogen is 77 [[Kelvin|K]].*Room [[temperature]] is approximately 293 [[Kelvin|K]] on the [[Kelvin]] scale.
