Question :
How does the water kept in an earthen pot (matka) become cool during summer?Submitted on 23/12/2023 | Answered by Vandana RanaAnswer :
The water kept in an earthen pot remains cool even in summer because of evaporation. Earthen pot has a large number of tiny pores in its walls and some of the water molecules continuously keep seeping through these pores to outside the pot. This water evaporates continuously and takes the latent heat required for vaporization from the remaining water.In this way, the remaining water loses heat and gets cooled.
