Formula of Latent Heat The heat of vaporization, (H v or H vap) is the amount of thermal energy required to convert a quantity of liquid into a vapor.It can be thought of as the energy required to break the intermolecular bonds within the liquid.

According to its phase, it has different names like the heat of condensation, the heat of vaporization, etc. Journal of Applied Meteorology and Climatology. Latent heat = Q/M = 200/10 = 20k.cal. Latent heat is the amount of heat added to or removed from a substance to produce a change in phase. The latent heat of vaporization ΔH corresponds to the amount of energy that must be supplied to the system to convert a unit amount of substance from the liquid to the vapor phase under conditions of equilibrium between the two phases.
