Question

The heat absorbed when 1 kg of a liquid changes to the gaseous state at its boiling temperature is known as
i) latent heat of fusion
ii) latent heat of sublimation
iii) latent heat of vaporization
iv )specific heat

Answer 1

Answer:

..................iii) latent heat of vaporization.....................

Explanation:

The heat energy required to change the state of unit mass of a substance is called latent heat. As the given liquid is of unit mass (1kg) and we have to change its state into gas, therefore heat needed will be specific latent heat of vaporisation.

Answer 2

Explanation:

latent heat of vaporization
