Latent Heat
Latent heat is the energy (see note below) released or absorbed during a phase change, where the temperature does not change. This is because all of the heat is used up in the phase change, rather than into changing temperature. Latent heat is actually the total amount of enthalpy (a kind of energy) necessary to accomplish a phase change.
