A		water is always at a lower temperature than the surface.
B		the water absorbs energy from the surface for its ΔHvaporization as it evaporates.
C		the presence of water vapor in the air keeps surfaces cool.
D		the concentration of various contaminants increases, increasing the boiling point of the water and requiring more energy from the surface to evaporate.
