Detailed Solution

Assertion is false but the reasoning is true.
The temperature of the liquid decreases as the liquid gets evaporated. Temperature decreases because the surface molecules take some amount of energy during evaporation. Thus, after evaporation, cooling is observed. In an evaporating molecule, the kinetic energy of the molecules is directly proportional to the absolute temperature.
