Heat of vaporization Definition:

  • Heat of vaporization is the quantity of heat a liquid must absorb for 1 g of it to be converted from the liquid to the gaseous state.

Heat of vaporization Explanation:

The heat of vaporization is also called the enthalpy of evaporation and it is the energy needed to convert a molecule to gaseous state. For example the heat of vaporization of water is 100 degrees which is required to boil the water and convert it into vapors. The enthalpy of vaporization is basically 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 pressure at which that transformation takes place. The enthalpy of vaporization is often quoted for the normal boiling temperature of the substance.
