WebThe enthalpy of vaporization(symbol ∆Hvap), also known as the (latent) heat of vaporizationor heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressureat which that transformation takes place.
