Question

how dose evaporation cause cooling?

Answer 1

 particles in the liquid have a lower average kinetic energy than before, so the liquid cools down as evaporationhappens. This is why sweating cools you down. The sweat absorbs energy from your skin so that it can continue to evaporate

Answer 2

evaporation causes cooling because during evaporation the particles of the liquid absorb energy from the surroundings to regain the energy lost during evaporation the absorption of heat from the surrounding makes the surrounding cool example when we spray deo on our hand .
