This Cooling effect is based on the principle of Evaporative Cooling or simply cooling thru evaporation.....An earthen pitcher has pores through wich water propagates or oozes out and evaporates...the heat required for evaporation is taken up by the liquid itself...hence the heat pays off and the water gets cooled.

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.
How evaporation cools water in earthen pot?
Evaporation is an endothermic process.
In domestic pitcher why water get cool?
water in pitcher becomes cool because pitcher has small pores on its surface and the water evaporates from pores by using heat of water. in this way evaporation takes the heat and water in the pitcher becomes cool
What do all materials do except water do they cooled?
They freezee
When water at 4 degrees Celsius is cooled it does it contract?
No. When water is cooled it contracts up to 4 degrees Celsius and then it begins to expand till 0 degrees Celsius. This is called the anomalous expansion of water.

Why does water get cooled in an earthern pitcher?
the earthen pitchers have small pores from which water gets continuously leaks forming a film of water.this layer continuously is evaporated . evaporation absorbs the heat equal to latent heat of vaporization from the water or the surroundings thus causing cooling.
Why is the water in the earth pot cool?
Earthen pot has tiny pores on its surface. The water oozes out from these pores. It then evaporates taking energy known as "latent heat" from the pot. Thus, the temperature of the water inside decreases. This process goes on and this is the reason why the water in earthen pot is cooled faster.
What is an earthen pitcher made of?
An earthen pitcher is a round shape vessle made by moist clay.Moist clay is placed on a circulating wheel and the clay is then given the shape of a round vessle.It is then kept for few days as the water of clay evaporates.Then the vessle is placed in the kiln at a very high temprature to streangthen the vessle for few hours.This round shape vessle is than called"EARTHEN PITCHER".It is widely used to store drinking water in INDIA,PAKISTAN,SRI LANKA,BANGLA DESH,MAYAMAAR,CHINA....and host of other contries as the water oozes out from the very small pours of picher and provides cooling by evaporation.
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.
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 a Honda goldwing 1100 oil cooled or water cooled?
Water cooled.
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.
Is Air cooled vs water cooled pocket bikes?
water cooled is better
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
Is a 1995 vlx Honda shadow air cooled or water cooled?
Its both air and water cooled.
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.
