Latent Heat

Latent means hidden.


》Latent Heat is the heat energy which can be added or removed from a substance without a change in temperature.


》Latent Heat is absorbed or released during changes of state

Change of State

Latent Heat of evaporation is the heat absorbed during the process of evaporation - the particles in the liquid state have to be separated before they can move further, this is an increase in kinetic Energy.

Continued

Latent Heat of fusion is the heat absorbed during the process of melting - the particles in the solid have to be separated before they can move further and this is an increase in kinetic Energy.
