Evaporation causes cooling because the process requires heat energy. The energy is taken away by the molecules when they convert from liquid into gas, and this causes cooling on the original surface.

• 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.
