उत्तर
‘Surahi’ is made of clay which is porous (being not glazed) and so water oozes out (creeps out) and wets its entire surface. Form its outer surface, water get evaporated taking latent heat needed for evaporation from inside water as well as surrounding air and so the temperature of inside water falls.
