# 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)
