Question

How does the water keept in an earthen pot become cool during summer?​

Answer 1

Answer:

The water kept in an earthen pot seeps into the small pores in the pot and evaporates from the surface of the pot. The heat required for evaporation is taken from water inside the pot, thus cooling the water stored inside. This is the reason why on hot summer days water remains cool in earthen pot.

Answer 2

• An earthen pot has small pores in its walls. When water is poured into it , some of it seeps through these pores onto its outer surface. On reaching there, it evaporates . The heat required for evaporation is taken from the earthen pot and from the water in it. As a result, the water in an earthen pot gets cooled down.
