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.

What else can I help you with?
Why water filter is provided at water inlet of water cooler?
So that the internals of the cooler don't get gunked up by precipitates that come out of suspension when the water is chilled. Solubles will still precipitate out.
Difference between a boiler and water heater?
A hot water heater is the storage tank of water that is responsible for the supply of hot water to the many fixtures in the house, such as showers and sinks. It does NOT supply heat for the home itself. There are two basic types of water heaters, one that runs on gas or some other fuel and one that runs on electric. A boiler on the other hand IS responsible for the heating of a home itself. Water or steam in a boiler reach much higher temperatures than the water in a hot water tank and therefore its used for heating and not drinking water or potable water. In a steam system for heating, pipes run throughout the house from the boiler carrying steam that eventually gives off its heat at the many radiators. In a hydronic system for heat, smaller pipes carry hot water to various baseboards around the house that release the heat using circulator pumps to push the water through and back to the boiler.
How do you make a water column gauge?
With a U form glass tube and filled with water.
What the difference between extraction and bleeding in steam turbine?
bleed is amount of steam output from turbine through pipe and exit from final stage of turbine . this bleed enter to feed water heater (low and high) and deaereator to increase unit efficiency or rather bleed is the amount of steam drained out of the steam turbine during the expansion of steam and this rejected heat energy is used to heat the feed water supplied to the boiler...........
Why water drops fall from silencer of car?
The silencer is very sad and the water drops are its tears.
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.
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.
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.
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 an earthen pitcher gets cools down in summer?
The porous nature of the earthen pitcher allows water to seep through its walls. As the water evaporates from the surface of the pitcher, it absorbs heat energy from the remaining water inside, causing it to cool down. This phenomenon is known as evaporative cooling and helps regulate the temperature of the water stored in the pitcher.
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.
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.
How is water cycle altered during drought?
There is no precipitation during droughts. Water becomes scarce.
What happens to the Nile in summer?
The evaporation problem becomes worse and the water level drops.
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
Small problem and fix it before it becomes a major problem Give an example?
A leak in an earthen dam, if fixed in time the dam will continue to hold water, if left unfixed the dam will rupture.
