Question

what do you understand by laten heat of fusion and laten heat of vapourisation?​

Answer 1

Explanation:

The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization. ..

Answer 2

Answer:

1.The amount of heat required to change 1 kg of a substance at the temperature of its melting point from the solid to the liquid state without changing temperature.

2.The amount of heat energy required to change 1 kg of a liquid to gas at atmospheric pressure

at its boiling point is called latent heat of vaporization.
