How does Matka keep water cool?
The cooling process works through evaporative cooling. Capillary action causes water to evaporate from the mini-pores in the pot, taking the heat from the water inside, thus making the water inside cooler than the outside temperature.
Which process enables our than pots Matkas to keep water cool?
Water kept in earthen pot remains cool because of evaporation taking place at large scale due to large area ( mouth of earthen pot + tiny gaps present at the side walls of pot ) present for evaporation. As during evaporation, hot heat energy also gets lost with particles and replaced by cold heat energy.
Why do pitchers keep water cool?
Cooling is caused by evaporation. Some heat energy is utilised during the process of evaporation. Since this energy is taken from the water itself, it leads to a lowering of temperature in the remaining amount of water.
Why does water kept in mud pots remain cool in summer?
Solution: The water kept in an earthen pot seeps into the small pores in the pot and evaporates from the surface of the pot. The heat required for evaporation is taken from water inside the pot, thus cooling the water stored inside. This is the reason why on hot summer days water remains cool in earthen pot.
Does clay keep water cold?
The earthen pots used to store water is made of clay, which is porous and thereby naturally keeps the water cool. This also means that you don’t have to depend on a refrigerator or be at the mercy of electricity to have access to cool water during the summer.
Which object clay object is used to keep water cool in summer?
Clay pots are used to store drinking water mostly in summers because they help to keep the water cool.
Why is well water warm in winter?
We know, well water is absorbed from deep inside the ground. At that surface, water absorbs the heat from the earth’s core and remains hot. When the same water is brought to the surface, the temp. So, well water is felt to be warmer in the morning during the winter.
How does water in a swimming pool remains comfortably cool on a hot summer day?
Water in swimming pools remains cool even dur-ing hot summer. This is because water has high ,specific heat capacity and requires large amount of heat for raising the temperature.
