Answer – The water molecules absorb the heat molecules present in our body and convert them into gas molecules. Evaporation is the process by which liquid or solid is converted into vapours.
When the water molecules are converted into gas molecules, their energy is taken away causing a cooling effect on our body. The heat from the atmosphere is decreased due to evaporation, causing a cooling effect in the atmosphere.
Earthen pots are also able to cool the water lower than the temperature of the room due to the effect of evaporation. The rate of cooling is more in the summer season and less in the rainy season, this happens due to the presence of humidity in the atmosphere.
