The input energy required to change the state from liquid to vapor at constant temperature is called the latent heat of vaporization. When a liquid vaporize at the normal boiling point the temperature of the liquid will not rise beyond the temperature of the boiling point.

Using the equation for a change in temperature and the value for water from Table 14.7.1 14.7. 1, we find that Q = mLf = (1.0 kg)(334 kJ/kg) = 334 kJ Q = m L f = (1.0 k g) (334 k J / k g) = 334 k J is the energy to melt a kilogram of ice. This is a lot of energy as it represents the same amount of energy needed to raise the temperature of 1 kg ...

In thermodynamics, the enthalpy of vaporization (symbol ∆Hvap), also known as the (latent) heat of vaporization or 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.
