Question

ਕਿਸ ਪ੍ਰਕਿਰਿਆ ਕਾਰਨ ਗਰਮੀਆਂ ਵਿੱਚ ਮਿੱਟੀ ਦੇ ਘੜੇ ਵਿੱਚ ਰੱਖਿਆ ਪਾਣੀ ਠੰਢਾ ਹੋ ਜਾਂਦਾ ਹੈ ? Due to which process the water kept in the earthen pot cools down in summer?​

Answer 1

Answer:

The cooling process works through evaporative cooling. Capillary action causes water to evaporate from the mini-pores in the pot, taking the heat from the water inside, thus making the water inside cooler than the outside temperature. Hence it is used only during summer and not in winter.
