Question

evaporation produces cooling of the liquid explain

Answer 1

During evaporation the molecule having high energy are able to overcome the attractive force of other molecule and escape as vapour. As the proportion of high kinetic energy molecule in the liquid decreases, the average kinetic energy of the liquid decreases, resulting in the internal cooling of the liquid

Answer 2

On an empty vessel, the liquid keeps on evaporating. During evaporation,it gains energy lost during evaporation from the surrounding. Thus,makes the surroundings cool
