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.

∙ 14y agoEvaporative cooling. Water seeps through the pot and evaporates from the outer surface. In evaporating, the water requires a substantial amount of energy, which it draws from the pot and its contents as heat - the pot cools. Lick your own finger and gently blow across it - you will sense evaporative cooling of your finger.

∙ 7y agoDuring 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.

∙ 11y agoThe earthen pot is made of clay or of other porous earth materials. These vessels have small miniature pores (invisible to naked eye) through which water in the pot continuously seeps out. This water as it seeps out evaporates taking the latent heat away from the pot and the water stored in it. Removal of this latent heat results in cooling of the water inside the container. This phenomenon is also known as "evaporative cooling".

∙ 9y agoWater will remain cool in an earthenware pot because the clay is too dense to allow heat in. Water placed in this type of clay pot will stay cool for hours without using ice.

∙ 10y agoWater gets cooled in an earthen pot from the pores in the pot. This will cause evaporation and will make the water cool down. Earthen pots are used all over the world.

- The earthen pot is porous with lot of tiny pores on it , the water oozes out through these pores & the water gets evaporated at the surface of the pot thereby causing cooling effect. This makes pot cold & the water inside the pot cools by this process.
Thank you.....

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 evaporation cools water in earthen pot?
Evaporation is an endothermic process.
Why summer time of water save?
People and plants require more water during summer months. People also use more water for recreational purposes. There is also typically less rainfall during the summer, therefore greater conservation efforts are necessary.
Where does the warm water in a normal year?
Warm water in a normal year typically occurs during the summer month. July and August are usually the warmest and cause the water to heat up. The coldest water will be during the winter.

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.

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.
Is it safe to use water kept in earthen pots?
Depends whether the earthen pot is baked or not, if it is, it's safe to keep it.
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
Why aerated water bottles kept under water during summer?
Because the air expands during summer, which leads to the breaking of bottle; so to avoid this, it is kept under water.

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.
