LATENTHEAT
Latent heat
Latent heat is the energy released or absorbed by a body or a thermodynamic system during a constant-temperature process. A typical example is a change of state of matter, meaning a phase transition such as the melting of ice or the boiling of water. The term was introduced around 1762 by Scottish chemist Joseph Black. It is derived from the Latin latere . Black used the term in the context of calorimetry when referring to the heat transferred that caused a change of volume while the thermodynamic system was held at constant temperature.The above text is a snippet from Wikipedia: Latent heat
