Evaporation occurs when energy is supplied to liquid molecules to separate molecules. So you have to discuss about evaporation process when a liquid is being heated.


Kinetic theory of gases states that molecules move at high speeds with weak forces of attraction between molecules. Therefore when liquid molecules are supplied with energy, the attractive forces holding the molecules together are broken and the molecules move with greater speed as they have more energy. This causes molecules to move further away from each other and attractive forces between molecules to become weaker. This is the process of evaporation explained using kinetic theory of gases.
