Answer 2

Explanation:

As we switch on the fan an air current flows and we know evaporation of water is directly proportional to wind as wind blows the water molecules present on the surface of our skin from the sweat and thus the heat needed for latent heat of evaporation is taken from our body which decreases our body temperature and a cooling effect is created
