The addition or removal of latent heat causes thermodynamic phase changes in a substance.
What is a latent heat?
It refers to the amount of heat required to convert the solid into liquid or vapor and a liquid into a vapor without changing the temperature.
The two types of latent heat are:
Latent heat of fusion: This is the amount of heat energy released or absorbed when the solid converted to liquid at atmospheric pressure at its melting point.
Latent heat of vaporization: This is the amount of heat energy released or absorbed when the liquid converted to vapor at atmospheric pressure at its boiling point.
