When temperature of water in earthen pot is less than temperature outside, will earthen vessel help in maintaining the temperature of water inside constant (or) will it help by decreasing the temperature inside?
Puneeth423 said:I think it only helps in maintaining temperature of water inside vessel constant. If you take the same water in some steel vessel, as it is a better conductor, it will absorb heat from surroundings and transfer heat to water inside making it hotter. In case of earthen vessel, the water in pores doesn't decrease the temperature of the water inside, it only helps in maintaining temperature if we follow rules of heat transfer.
Chestermiller said:The the presence of the pores will enable water to reach the outer surface of vessel, where it can evaporate. This will cool the outer surface.
Puneeth423 said:This will not cool the vessel. As the temperature outside is more than the temperature inside the vessel, it will will take heat from outside and evaporates. This will help in maintaining the temperature of water inside but doesn't cool the water inside. It will not allow the heat to flow from outside to inside.
sophiecentaur said:Why should it not reduce the temperature of the water? Start with water at room temperature and some of the energy for evaporation will come from the water inside - reducing the temperature. Why do people die of exposure if that doesn't happen?
Yes that works to cool the water inside; and it's perhaps the main reason for its use in places without electricity. It's the simplest fridge in the world.Chestermiller said:The the presence of the pores will enable water to reach the outer surface of vessel, where it can evaporate.

An earthen vessel is a type of pottery that is made from clay and hardened by firing in a kiln. It functions as a container for holding liquids, food, or other items. It is also commonly used for cooking, storing, and serving purposes.
An earthen vessel is typically made from a specific type of clay that is porous and allows for the evaporation of water. This makes it ideal for cooking and storing food as the moisture can escape, preventing spoilage. It is also usually unglazed, giving it a rustic and natural appearance.
The type of clay used to make an earthen vessel can greatly impact its function. Porous clays allow for the evaporation of water, while less porous clays are better for holding liquids. The presence of minerals in the clay can also affect its strength and durability.
Earthen vessels have been used for centuries in various cultures for a variety of purposes. Some common uses include food storage, cooking, serving dishes, and decorative pieces. They can also be used for storing liquids such as water, wine, or oil.
To ensure the longevity and proper functioning of an earthen vessel, it is important to handle it with care and avoid exposing it to extreme temperatures. It is also recommended to season the vessel with oil before using it for cooking or storing food. Regular cleaning with warm water and a mild soap is also recommended to remove any buildup or residue.
