Question

How does the water kept in an earthen pot become cool during summer

Answer 1

In an open vessel the liquid keeps on evaporating. The particles of liquid absorb energy from surrounding to regain the energy lost during evaporation. This absorption of energy from the surroundings make the surrounding cold

Answer 2

It becomes cool due to evaporation.

• Water maintained in such a container gradually seeps into its microscopic pores.
• It then evaporates off the container's active surface.
• The specific heat typically needed for potential evaporation is extracted from the water inside the pot, which passively cools the water inside.
• As a result, the sparkling water in a container remains cold even on hot summer days.
