Why does clay pot keep water cold?

Water placed in earthen pots is evaporated from minuscule pores it has as it is made of mud particles. The earthen pot and water hence loses heat and this makes the water inside the pot cool. This evaporation of water produces a cooling effect.

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

Evaporates taking latent heat and removal of latent heat results on cooling. Earthen pots have small pores through which the water seeps and as evaporation leads to cooling of the substance.

Is clay pot safe for drinking water?

Clay pots are not just useful to cool the water but also to purify it naturally. The porous micro-texture blocks contaminants in the water and makes it relatively safe to drink.

Why does Matka keep water cool?

Cooling process 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.

Why do pitchers keep water cool?

Water remains cool in earthen pitcher due to the process of evaporation. Water gets cooled on evaporation. As the earthenware pitcher is concerned, they have small pores. Water tends to come out of pores and evaporates which results in cooling effect on the earthenware and water.

How does the water kept in earthen?

An earthen pot has many small pores. Water seeps out through these pores and evaporates from the surface of the pot. The energy needed for evaporation is taken from the water kept in the earthen pot. As a result, water kept in earthen pot becomes cool.

Why does water taste better in clay?

Since clay is porous, when you store water in the clay pot, evaporation happens. Clay has small holes at the microscopic level through which water seeps out and gains energy from heat to become gas and gets evaporated causing the water to cool.

Why is the water inside a clay pot cool?

The water inside the clay pot is cool due to the evaporation process. The clay pot has tiny pores in the surface and water gets evaporated very quickly through these pores. Due to this evaporation process, the heat of the water inside the pot is lost, which lowers the temperature of the water.

Why does water stay cool in ‘matkas’ (earthen clay pots)?

The only way the water oozing out of the matka can turn to vapour is by absorbing heat from the liquid within the matka and the matka itself. Due to this process of continuous absorption of heat from the water inside the matka, in a few hours, this water becomes cool. Why Does Water stay Cool in ‘Matkas’ (earthen clay pots)?

What happens to water kept in earthen pots when heated?

As a result, water kept in earthen pot becomes cool. Before making a clay pot, the clay is mixed with water moulded into the shape of pot and then the pot is heated. During heating, the water in the walls of clay pot gets evaporated and the places where water evaporated remains empty.

How does water stay cool in pots without boiling?

Surprisingly enough, the pots are exposed to blazing sunlight, yet the water within stays so cool. How is that possible? This is because of a physical process known as evaporation. When a liquid changes to a gaseous (or vapour) state without boiling, it is known as evaporation.
