Question

Define terms 'latent heat of fusion and latent heat of vaporization

Answer 1

Answer:

Latent heat of fusion :

The amount of the heat energy that is required to change the one (1) kg of solid into liquid at its atmospheric pressure is known as Latent heat of fusion.

Latent heat of vaporization :

The amount of the heat energy that is required to change the one (1) litre of liquid into gas at its atmospheric pressure of melting point is known as Latent heat of vaporization.

Answer 2

Latent heat of vaporization is the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure without changing its state.

Latent heat of fusion is the amount of heat energy required to change 1 kg of solid into liquid without changing its state.
