  • The amount of heat needed to change the state of unit mass of the body from solid to liquid or from liquid to gas without any change in temperature is called latent heat.
  • When the latent heat is given off the body in liquid state, it will convert to solid state and the body in vapour state will transform to liquid state.
  • This means the internal energy of the matter is reduced when latent heat is given off.
