Question

Latent heat of vaporisation of water is equal to the latent heat of fusion of ice.

• A. True
• B. False

Answer 1

The correct option is B False

Latent heat of fusion is the amount of heat required to convert a substance from its solid state to liquid state at constant temperature under atmospheric pressure. The latent heat of vaporisation is the amount of heat required to convert a substance from its liquid state to gaseous state at constant temperature under atmospheric pressure. Since both involve transformations of different physical states, their values will be different.
