Enthalpy of sublimation
|This article does not cite any references or sources. (December 2009)|
The enthalpy of sublimation, or heat of sublimation, is the heat required to sublime one mole of the substance at a given combination of temperature and pressure, usually standard temperature and pressure (STP). The heat of sublimation is usually expressed in kJ/mol, although the less customary kJ/kg is also encountered.
