Definition

energy (ISO 80000-5: Thermodynamics) necessary to be added or subtracted isothermally and isobarically to a system to completely undergo the phase transition

énergie (ISO 80000-5: Thermodynamics) devant être ajoutée ou soustraite de façon isotherme ou isobare à un système pour qu'il subisse une transition de phase complète

Notes

Mostly, molar or specific quantity is used and phase transition is expressed explicitly, e.g. molar latent heat of evaporation.

The subscript "pt" is the qualifier for the phase transition, which may be changed to e.g. "l-g".

The term "enthalpy of phase transition" is mainly used in theory.

En général, une grandeur molaire ou massique est utilisée et la transition de phase est exprimée explicitement, par exemple chaleur latente molaire d'évaporation.

L'indice inférieur «pt» qualifie une transition de phase et peut être remplacé par exemple par «l-g».

L'expression «enthalpie de transition de phase» est essentiellement utilisée en théorie.
