Question

define latent heat of vaporization and latent heat of fusion

Answer 1

Latent heat of fusion refers to the amount of heat required to convert 1 gm of a solid to a gas without converting into a liquid under normal pressure.
Latent heat of vaporization refers to the amount of heat required to convert 1 gm of a liquid to a gas under normal pressure.

Answer 2

LATENT HEAT OF VAPORISATION :- Laten heat of vaporisation is the amount of heat energy required to change 1 litre of a liquid to gas at atmospheric pressure and St its boiling point .

LATENT HEAT OF FUSION :- Latent heat of fusion is the amount of heat energy required to change 1 kg of solid into liquid at its melting point .
