Latent Heat of Melting of some common Materials

The latent heat of fusion when changing between solid or liquid state of some common materials as aluminum, ammonia, glycerin, water and more

The specific latent heat of fusion of a substance is the amount of heat required to convert unit mass of the solid into the liquid without a change in temperature.

The latent heat of melting some common solids are indicated in the table below:
