Liquid vaporization into a gaseous process: endothermic;

Gaseous liquefaction into a liquid process: exothermic;

Solid state melting into a liquid process: endothermic;

Liquid solidification into a solid process: exothermic;

Solid state sublimation into a gaseous state process: endothermic;

Gaseous solidification into a solid state process: exothermic;

 

Note: Solid-liquid transitions will be used in ice storage systems; The changing state will store large amounts of energy: latent heat.
