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.
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.
Because it evaporate the water in summer season
Water warms and cools slower than land. This is because water has a higher specific heat capacity compared to land, meaning it requires more energy to change its temperature. This property of water plays a role in moderating the climate of coastal areas.
When water vapor cools and condenses into a cloud, this process is called condensation. This happens when the water vapor reaches its dew point temperature and changes back into liquid water droplets, which then cluster together to form clouds in the atmosphere.
Condensation occurs as water vapor cools in the atmosphere, leading to the formation of clouds or fog.
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.
Evaporation cools water in an earthen pot by absorbing heat energy from the surrounding environment as the water molecules transition from liquid to vapor. This process causes a drop in temperature within the pot, making the water inside cooler than the external temperature. The porous nature of the earthen pot allows for better airflow and evaporation, enhancing the cooling effect.
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.
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.
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.
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
Evaporation cools it.
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.
An earthen pitcher, often referred to as a clay pitcher, is a traditional container made from natural clay that is shaped and fired to create a durable vessel. These pitchers are commonly used for storing and serving liquids, such as water, milk, or traditional beverages. The porous nature of clay allows for evaporation, which can help keep contents cool. Earthen pitchers are valued for their aesthetic appeal and cultural significance in many regions around the world.
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.
Earthen pots are better than glass pots for storing cold drinking water in hot climates because they naturally keep water cooler through a process called evaporative cooling. The porous nature of clay allows moisture to escape, which cools the water inside as it evaporates. Additionally, earthen pots often impart a slight earthy taste to the water, enhancing its flavor, while glass pots do not have this cooling effect or flavor enhancement. This makes earthen pots a more effective and enjoyable option for keeping water cool in hot weather.
