Latent Heat

Latent heat is defined as the heat or energy that is absorbed or released during a phase change of a substance.

Types of Latent Heat :-

1. Latent heat of fusion: Let us suppose we have one kg of ice and we have to convert it into water, the amount of heat required to do this is called as latent heat of fusion. In general amount of heat required to melt the substance of unit mass from solid to liquid or the amount of heat required to be removed from the unit mass of substance to freeze it from liquid to solid is called as latent heat of fusion denoted by ‘lfu’.

2. Latent heat of sublimation: Some of the substances like naphthalene get directly converted from solid to gaseous state when kept in the open atmosphere. The amount of heat required by the unit mass of substance to convert directly from solid to gaseous phase or the amount of heat required to be removed from the gaseous substance to change it to the solid phase is called as latent heat of sublimation denoted by ‘lsub’.

3. Latent heat of vaporization: We have seen the example for boiling water. The amount of heat required by the unit mass of substance to vaporize from liquid to gaseous state or the amount of heat required to be removed from the unit mass of substance to condense from the gaseous to liquid phase is called as latent of vaporization denoted by ‘lfu’.
