Answer:

This is because for evaporation, liquids absorb heat energy from the surroundings. Since the surroundings loose heat energy, they become cool. Hence, evaporation causes cooling effect.

Explanation:

Evaporation is the phenomena of vaporizing of a liquid at a temperature below than its boiling point.

For evaporation, the liquid will have to absorb heat energy to break inter-molecular forces of attraction and change their state from liquid to gas. They absorb this heat energy from the surroundings, for example, our hand. This makes our hand to loose heat energy and as a result, our palm becomes cool. Thus, evaporation causes cooling effect.
