Question

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

Answer 1

This is because of evaporation. When a liquid changes to a gaseous (or vapour) state without boiling, it is known as evaporation.

The earthen pot is made of mud and has many minute pores (extremely small holes). Through these pores that the water, placed inside the earthen pot oozes out. Now, to evaporate, the water needs to absorb heat, which will change it to vapour

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

✔Well, the Answer is related to the cooling effect of Evaporation . The earthen pot has small pores . The water from the pot evaporates from these pores leading to a cooling effect . This helps to keep water cool in summers !


⭐What is the cooling effect of Evaporation ?

◾We know that Evaporation is a Surface phenomena . So the particles on the surface evaporate by gathering energy from surroundings . This transfers into a cooling effect .
