Why is cooling caused in evaporation?
During evaporation, the liquid molecules with higher kinetic energy leave the liquid surface. As a result, the average kinetic energy of the remaining liquid molecules continues to fall. Consequently, the temperature of liquid falls (since KE ∝ T) or cooling is caused by evaporation.
