Solution
The latent heat of vaporization of a liquid is the quantity of heat in joules required to convert 1 kilogram of the liquid (at its boiling point) to vapour or gas, without any change in temperature. For example, the latent heat of vaporization of water is 22.5 × 105 joules per kilogram (or 22.5 × 105 J/kg).
