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

Question

Answer

Because the water seeps through the holes present in the pot and evaporates. Also evaporation causes cooling that it why the water kept in earthen pots become cool during summer and also the rate of evaporation increases in summers due to increased Temperaturethat's ol :)

Answer

An earthen pot has small pores in its walls. When water is poured into it, some of it seeps through these pores onto its outer surface. On reaching there, it evaporates. The heat required for evaporation is taken from the earthen pot and from the water in it. As, a result, the water in an earthen pot gets cooled down.

Answer

Introduction:
Earthen pots, also known as matkas, have been used in India for centuries to store and cool water. The water kept in an earthen pot becomes cool during summer due to a natural process of evaporation and heat transfer.

Evaporation Process:
The porous nature of the earthen pot allows water to seep through its walls and evaporate from its surface. When water evaporates, it absorbs heat from the surrounding environment, which causes the temperature of the remaining water to decrease. This process is known as evaporative cooling.

Heat Transfer Process:
In addition to evaporation, the earthen pot also facilitates heat transfer between the water inside and the outside environment. The porous walls of the pot allow heat to escape from the water to the surrounding air. This process is known as convection, where heat is transferred through a fluid (air in this case).

Capillary Action:
Another important factor that contributes to the cooling effect of earthen pots is capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of external forces. The porous walls of the earthen pot allow water to move through it and spread on the surface, increasing the surface area for evaporation and heat transfer.

Conclusion:
In conclusion, the water kept in an earthen pot becomes cool during summer due to a combination of evaporation, heat transfer, and capillary action. This traditional method of cooling water is not only effective but also eco-friendly and sustainable.

Answer

Due pores of matka by which water vaporise so water is cool in summer

Answer

Due to evaporation.

Answer

There are some pores in an earthen pot through which the liquid inside the pot evaporates. This evaporation makes the water inside the pot cool. In this way, water kept in an earthen pot becomes cool during summers

Answer

Due exchange of gases takes place
