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

It’s all about evaporation coolness. The cooling effect of water in an earthen pot during summer is a result of a clever process called evaporative cooling.

Earthen pots are like natural coolers – they’re made of clay with tiny holes. When water is inside, it seeps through these holes and sits on the pot’s surface. Sun heats things up, causing some water on the surface to evaporate. Evaporation needs heat energy, and it takes this energy from the rest of the water and the pot. That’s why they get cooler. The evaporating water carries away heat, making things feel refreshing. It’s like nature’s way of giving us a cool sip on a hot day!”
