Question

what is latent heat of vapourisation ?​

Answer 1

Answer:

It is the amount of heat energy required to change from liquid to gas without rise in temperature is known as latent heat of vapourisation.

e.g. latent heat of vapourisation of water is 22.5 ×10^5 joule per kg.

Answer 2

.The enthalpy of vaporization, also known as the heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance, to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressure at which that transformation takes place.
