Question

what is evaporation how is it cool the surface​

Answer 1

Answer:

Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure. Evaporation is a fundamental part of the water cycle and is constantly occurring throughout nature.

When a liquid evaporates, its molecules convert from the liquid phase to the vapor phase and escape from the surface. ... Since the molecule is taking heat with it as it's leaving, this has a cooling effect on the surface left behind.

Answer 2

The process of conversion from liquid to vapour state on exposure to the atmosphere is called evaporation. It occurs on absorbing heat. Evaporation cools the surface as it absorbs heat from the surface to change into vapour state.
