Question

Why water kept in earthen pot becomes cool during summer .com?

Answer 1

Because the seeping water took away the latent heat of vaporization from the pot...........

Answer 2

$\mathfrak{\huge{\red{\underline{\underline{Answer}}}}}$

Water placed in earthen pots is evaporated from minuscule pores it has as it is made of mud particles. This evaporation of water produces a cooling effect. Some of the heat energy that is generated is used in the process of evaporation. Hence, water stored in earthen pots tends to become cooler in summer.
