Enthalpy of Vaporization Calculator

The molar enthalpy of vaporization represented as ΔHvap, referred as the molar heat of vaporization or evaporation. The amount of energy needed to change one mole of a substance from the liquid phase to the gas phase at constant temperature and pressure is molar heat of vaporization. To find molar heat of vaporization, enter the values of initial temperature, final temperature, vapour pressure at temperature T1 and vapour pressure at Temperature T2 in enthalpy of vaporization calculator.
