How does water stored in a mud pot remain cool?
Water molecules are constantly in motion, with varying speeds and energies.
The temperature we measure reflects the average kinetic energy of all water molecules.
Fast-moving molecules escape from the water surface into the air, lowering the water’s average kinetic energy.
This evaporation process leads to a decrease in water temperature.
Mud pots have numerous pores that provide a large surface area for evaporation.
The increased surface area enhances the evaporation process, cooling the water more effectively.
The cooling effect of the mud pot is more pronounced when the external temperature is higher, promoting faster evaporation.
The water in the pot never freezes because the pot is not a closed system.
It absorbs heat from the surroundings, leading to an equilibrium temperature where heat loss and gain are balanced.
To freeze water, further removal of heat is required beyond the equilibrium temperature.
