Latent Heat of Melting common Materials
Latent heat of fusion when changing between solid or liquid state for common materials like aluminum, ammonia, glycerin, water and more.
The latent heat of fusion of a substance is
- the amount of heat required to convert a unit mass of the solid into liquid without change in temperature
The latent heat of melting for some common solids are indicated below:

Heat Required to Melt a Solid
The heat required to melt a solid can be calculated as
q = Lm m (1)
where
q = required heat (J, Btu)
Lm = latent heat of melting (J/kg, Btu/lb)
m = mass of substance (kg, lb)
Example - Required Heat to melt Ice to Water
The heat required to melt 10 kg of ice to water can be calculated as
q = Lm m
= 334 103 (J/kg) 10 (kg)
= 3340000 (J)
= 3340 (kJ)
