Why does evaporation cause cooling?

Since the kinetic energy of a molecule is proportional to its temperature, evaporation
proceeds more quickly at higher temperatures. As the faster-moving
molecules escape, the remaining molecules have lower average kinetic
energy, and the temperature of the liquid decreases.

Answer:
This is because the process requires heat energy.The energy is taken away by the molecules when they convert from liquid into gas,and this causes cooling on the original surface.
