Specific Latent Heat
The amount of heat required to change the phase of a substance depends on the mass and the type of material of the substance.
A small ice cube melts quickly but a large block of ice melts very slowly.
100 J of heat energy can melt a large amount of wax, but the same amount of heat can only melt a small amount of iron.
The specific latent heat of a substance is the amount of heat required to change the phase of 1 kg of the substance at a constant temperature.
