The [[triple point]] of any [[pure substance]] is that combination of temperature and pressure at which all three phases of that substance (solid, liquid, and gas) coexist simultaneously.

The [[triple point]] of any [[pure substance]] is that combination of temperature and pressure at which all three phases of that substance (solid, liquid, and gas) coexist simultaneously in [[thermodynamic]] equilibrium.

 

The triple point of [[water]] is used to define the [[Kelvin]] temperature scale. It occurs at a temperature of 273.16 K = 0.01 °C = 32.018 °F.
