Question

Water stored in an earthen vessel becomes cool. Explain.

Answer 1

• Water stored in an earthen pot becomes cool due to evaporation.
• An earthen pot consists of a number of tiny pores on its wall.
• Water gets continuously evaporated through these pores in the form of water pores.
• During evaporation, heat is required which is taken from the water inside the vessel.
• This process produces a cooling effect and keeps the water cool.
