On a hotday you sweat. As it evaporates it cools you. Use particle theory to explain how evap produces coolin?

Answer 1

I don't know which particle theory you're talking about, but as a liquid changes to a vapor it cools because the molecules with higher kinetic energy evaporate first and carry the heat off with them. Since the gas is free to move, it doesn't put this energy back into the liquid.

Answer 2

when the water evaporates from your body, the total number of collisions on your body is reduced, and the average kinetic energy (temperature) is decreased.

Answer 3

easy the wind hits the sweat, the sweat cools, walla.  ur cooled off.
