Question 4
During summer, water kept in an earthen pot becomes cool because of the phenomenon of
(a) diffusion
(b) transpiration
(c) osmosis
(d) evaporation

Answer 1

During summers, earthen pots are used to cool the water down.In these pots water gets evaporated easily through the pores present. During evaporation water gets converted to its vapours using the heat energy from the water itself.This lead to the lowering of temperature withtin the pot and cools the water down. Hence, option (d) is correct.
