Evaporation causes cooling. This is based on the fact that when a liquid evaporates, it takes (or draws) the latent heat of vaporization from "another matter" which it touches. This "another mater looses" heat and gets cooled. This is how evaporation causes cooling.
E.g.- When perfume falls on our hand, our hand feels cool because perfume is a volatile liquid and gets evaporated rapidly taking away the latent heat of vaporization from our hand.
