The enthalpy of sublimation, or heat of sublimation, is the heat required to change one mole of a substance from solid state to gaseous state 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.
