HI NIHALA

WHEN WE SWEAT IN HOT ATMOSPHERE, OUR BODY RELEASES WATER IN FORM OF SWEAT. DUE TO HEAT, THIS WATER PRESENT IN FORM OF SWEAT EVAPORATES. WHEN THIS WATER EVAPORATES, OUR BODY FEELS AN COOLING EFFECT DUE TO EVAPORATION PROCESS.

NOTE THAT IF THIS WEATE IS SIMPLY REMOVED USING TOWEL, NO EVAPORATION TAKES PLACE AND HENCE NO COOLING EFFECT IS FELT

THANKS

Evaporation causes cooling effect,
For Ex: When our body is wet water on its surface gets heated up and evaporated by the heat in the body as we know heat transfers from high temp to low temp it tranfers from body to surrounding, this makes body lose heat and feel cool. This is how evaporation causes cooling effect.
