How does the water kept in an earthen pot become cool during summer?
An earthen pot has small pores in its walls. When water is poured into it, some of it seeps through these pores to 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.
Short Answer how does the water kept in an earthen pot matka become cool during summer?
Evaporative cooling.During the process of evaporation ,air takes in heat, thus cooling down the surrounding areas.In other words, particles of liquid absorb energy from the surroundings to regain the heat lost during evaporation,thereby cooling nearby objects.Same is the case with an earthen pot.
How does the water kept in an earthen potbecome cool during summer?
Earthen pots are made of mud. Mud structures are porous and have microscopic cracks and crevices. When you pour water on the inside, water enters these cracks and crevices and wets the pot throughout. Now, look what happens to temperature. After about 20 minutes or so, depending on the size of earthen pot, the temperature of water and pot becomes same due to heat transfer. Now, let us look at the outside surface of the pot. This pot is now wetted by water from the inside, and hence the outer surface of the pot naturally contains water exposed to atmosphere. This water evaporate and carries along with it a certain amount of heat. By doing so, the pot is now a little cooler than before. Continued evaporation brings about a stable state, where the heat input to the water inside the pot is lost through the outer layer of the wetted earthen pot due to continued evaporation. If we want to increase the rate of cooling or further reduce the temperature, then cover the outer surface of the pot by thick cotton cloth or rag cloth and pour water on it. Hope this answers your question.Read more: How_does_the_water_kept_in_earthen_pot_becomes_cool_during_summerEarthen pots are made of mud.

Why does new earthen pot is preferable to old one to cool water?
The cooling of water in an earthenware pot is the result of evaporation of water from the outside of the pot, an old pot normally has too many residual chemicals in the pot walls which prevents the water from penetrating to the outside to be evaporated.
What is the name of an earthen pot to store water?
An earthen pot to store water is called a "matka" in India. It is commonly used to keep water cool in hot regions.
Water cools down in an earthen pot give reaseons?
Earthen pots have tiny holes in them through which some of the water keeps seeping. But it is not noticeable. The water which is now outside the earthen pot evaporates. Durin evaporation, the water gain heat energy from the surroundings to evaporate. Thus the surroundings and the water in the earthen pot loses heat energy and cools gradually.

Why water in old pot is not cooler when compare to new pot?
new earthen pots enable the water inside to seep outside to a certain extent which makes the surface of the pot damp.this moisture then evaporates and cools the water inside,but in older earthen pots seeping of water does not take place to an extent when it was new.therefore old earthen pots does not cool the water inside
How does water kept ina earthen pot become cool during summer?
The porous nature of the earthen pot allows water to seep through its walls and evaporate on the outer surface. This evaporation absorbs heat from the water inside, making it cooler. Additionally, the earth material of the pot itself can have a cooling effect on the water due to its natural properties.
How does water kept in an earthen pot become cool during summers?
Physics explains this principle well - when evaporation takes place, cooling occurs. This is because for evaporation to take place, the water needs to change into vapor or gas and this only happens when there is heat in the surroundings. So when the water absorbs heat, it evaporates and this makes the container or surroundings cooler. The earthen pitcher contains many pores or small holes. When water is poured into the pot, a small part of it exits through these pores and evaporates from the surface of the pot, thus making the pot (and remaining water) cooler than before.
Why does water in a closed glass jar become warmer than water in closed earthen jar at the same dimension?
Provided the earthenware pot is UNGLAZED, the water inside the pot will seep through the pot making it damp on the outside. The dampness on the outside then evaporates and cools the pot and the water in it. (Lick your finger then blow on it gently and you will find your finger feels cold). However, a glass bottle is impervious to water, so the outside remains dry and there is no evaporation and the water in the bottle does not cool.
Why water kept in earthen pot remains cold?
The earhern pots used for keeping water cool in summer have small pores in it.water seeps in these pores and evaporates.as evaporation causes cooling, earthen pots remain cool.

Why does the water kept in the earthen pot becomes cool even in summer?
During hot summer days, water is usually kept in an earthen pot (called matka) to keep it cool. Let us see how it gets cooled. The earthen pot has large number of extremely small pores (or holes) in its walls. Some of the water continuously keeps seeping through these pores to the outside of the pot. This water evaporates (changes into vapour ) continuously and takes the latent heat required for vaporisation from the earthen pot and the remained water. In this way, the remaining water loses heat and gets cooled. This is also an example of the cooling caused by evaporation. It should be noted that all the water on the earth does not gets evaporated due to the high value of the latent heat of vaporisation of water. It is much less effective in humid environments than arid ones since high humidity limits the amount of evaporation.
