Latent heat of fusion and vaporization
Latent heat of fusion and vaporization
Open in App
Solution
The specific latent heat of fusion, l, of a substance is the heat needed to change a mass of 1 kg the substance from a solid at its melting point into liquid at the same temperature.
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).
