Class 9 Chemistry Matter In Our Surroundings Evaporation

Evaporation

The three states of matter possess different rate of kinetic energy at different temperature. Due to increase in temperature the particles at the surface of liquid possessing higher kinetic energy are capable to break away from the forces of attraction of other particles present in the surrounding and vaporises. This process of conversion of liquid to vapour at any temperature below its boiling point is termed as evaporation.

For instance, the wet clothes laid outside in the sunlight becomes dry after some time due to the evaporation of water particles form the surface of the clothes.
