I know that the conventional explanation for this is that the water needs energy to evaporate so it conviniantly takes the heat energy from your body in order to do this. But first of all, why does the water need to evaporate in the first place? Because of the sun? Then it should be getting energy from the sun not from your body? I hope that you guys understand the question, this always seemed so obvious to me but then when I thought it over I got confused. Thanks!
