Question

define latent heat of vapourization

Answer 1

Answer:

When a material in liquid state is given energy it changes its state and becomes vapour. The energy absorbed during this process is called latent heat of vaporization. During this process the energy remains constant it does not changes because the heat gets used up in breaking the force of attraction between the particles. The latent heat of vaporisation of water is 2260kg.

Answer 2

Answer :

The energy required in calories to completely convert one gram of water to steam without increasing the temperature is called the latent heat of vaporization. It is called latent heat because it does not increase the temperature. 

Latent heat of fusion of ice is heat energy required in calories by one gram of ice to completely convert itself into water without increase in temperature
