The quantity of heat required to change a unit mass (or sometimes a mole) of a liquid to its vapor, the two phases remaining in equilibrium at constant temperature, most commonly the normal boiling point, i.e., the temperature of boiling at a pressure of 101.325 kPa. The convenient SI units are J/g, kJ/kg or kJ/mol. Because high polymers decompose without boiling, their heats of vaporization cannot be directly measured.
