*[[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.
*[[Kelvin]] is defined based on the [[Triple Point|triple point ]] of [[water]] (the temperature and pressure at which [[water]] can exist as a [[solid]], [[liquid]] or a [[gas]]) simultaneously, precisely 1/273.16 of the thermodynamic [[temperature]] of the [[Triple Point|triple point ]] of [[water]].
===Examples===
The [[temperature]] of [[liquid]] nitrogen is 77 [[Kelvin|K]].
Room [[temperature]] is approximately 293 [[Kelvin|K]] on the [[Kelvin]] scale.
