Water evaporates faster at higher temperatures, when its surface area increases and when exposed to moving air. The concentration of water and other substances in the surrounding air and air pressure also affect evaporat... More »

Water evaporates when molecules at the interface of water and air have enough energy to escape the forces that hold them together in the liquid. Evaporation, along with boiling, is a type of vaporization. More »
