How does the water kept iinan earthen pot(matka) Become cool during summer ???

Answer 1

The only way the water oozing out of the earthen pot can turn to vapour is by absorbing heat from the liquid within the earthen pot and the earthen pot itself. Due to this process of continuous absorption of heat from the water inside the matka, in a few hours, this water becomes cool.

the water kept in an earthen pot became cool during summer because, in earthen pot water get evaporated quickly through the pores of the pot and cooling is caused by evaporation. Some heat Energy is utilised during the process of evaporation, therefore water kept in earthen pot became cool during summer.
