COOLING EFFECTS OF EVAPORATION

 Why should we wear cotton clothes in summer?

In summer we perspire(sweat) more because of heat. This help  to keep our body cool. If we use cotton clothes in summer because cotton is a good absorber of water help to absorb sweat from our body and expose to atmosphere for easy evaporation. As result of evaporation of sweat heat energy is absorbed for our body and make our body cool.
