Question

Name the process responsible for cooling of water kept in earthen pot during summers.

Answer 1

Identifying the process that helps water kept in an earthen pot become cool during summer:

• The water kept in an earthen pot remains cool even in summer because of evaporation.
• Evaporation is the phenomenon of changing the liquid state to vapours by absorbing heat.
• An earthen pot has a large number of tiny pores in its walls and some of the water molecules continuously keep seeping through these pores to outside the pot.
• This water evaporates continuously and takes the latent heat required for vaporization from the remaining water.
• In this way, the remaining water loses heat and gets cooled.
