What determines the rate of evaporation of a liquid?
Firstly, from the kind of liquid: where the attractive force between the liquid molecules is less, the evaporation rate is higher. If you rub your hand with a cotton swab moistened with water and then ether, the feeling of cold will be more from the action of the ether, because it evaporates faster, and the heat removal from the skin surface is higher. Secondly, from the temperature of the liquid: the higher the temperature of the liquid, the more molecules with speeds sufficient to escape from the surface of the liquid into the air.
Thirdly, from the free surface area of the liquid.
Fourth, from the presence of wind above the free surface of the liquid. Individual liquid molecules that have fallen into the air can fall back into the liquid, but if there is wind, it will blow these molecules to the side.
