Question

why does ethanol evaporate faster than water?

Answer 1

Ethanol and is opropanol boil at a lower temperature than water, which generally means that they will evaporate quicker than water. The boiling temperature is largely determined by attractive interactions between the liquid molecules.

Answer 2

In order for a liquid to evaporate, the KE (hence velocity) of the molecules must be sufficient to escape the intermolecular forces at the surface of the liquid. ... So,ethanol would evaporate faster than water which means that ethanol has a more effective cooling effect than water.
