Question

Why is cooling always called during evaporation?

Answer 1

evaporation happens by taking the heat of the body present.Hence it causes cooling to the body
during evaporation the heat of the body goes away to convert the material to vapour

eg; put acetone into your hand....you will feel cold as it took your body's heat to evaporate hence causing coolness

Hope it helps:)

• The process of changing liquid into gas both below and at the boiling temperature is called Evaporation. Evaporation gain heat from the surrounding as a result there is a loss of heat in the surrounding the cooling process start and the surface become cool.
