Question

Why does evaporation causes cooling of a liquid system?

Answer 1

When evaporation occurs then than the liquid (mostly water) absorbs all the heat from the surroundings and take it with it and we feel cool. Evaporation causes cooling effect because the heat energy is abosorbed by surrounding particles.

Answer 2

• 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. This is the reason why evaporation produce cooling.
