Why water kept in an earthen pot is cooler than the water kept in a glass container?
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.
Why does the water kept in an earthen pot becomes cool because of the phenomenon of?
(d) Evaporation During summer, water kept in an earthen pot becomes cool because of the phenomenon of evaporation. An earthen pot has numerous tiny pores in its walls and some water molecules continuously keep seeping through these pores to outside the pot.
Why old earthen pots reduced cooling efficiency?
When water is held in such fresh earthen pot, part of the water bleeds out through these pores by capillarity and interfacial affinity and makes the outer surface of the pot rather wet. That is why earthen pots lose their efficiency in keeping the water cool after being used for a few years.
How do you increase the cooling of an earthen pot?
ECCs and clay pot coolers must be places in a shady and well ventilated location. Exposure to wind and good ventilation increase the evaporation process. The evaporative cooling device should be watered frequently enough so that the sand is kept wet at all times, in order to enable the continuous cooling process.
Why is water kept in earthen pots during 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.
How does the water kept in a matka become cool during summer?
An earthen pot has a large number of tiny pores on its body. Hence, a small amount of water seeps out from these pores a nd gets evaporated from the surface. Hence, the water inside the earthen pot keeps losing heat, thus remaining cool. Thus, water kept in an earthen pot (matka) becomes cool during summer.
How do earthen pots keep water?
Earthen pots can retain water and collect scum quickly….Try adding some chlorine tablets to your water to make the particles settle down.
- If you use a matka, keep it covered at all times to prevent insects, dust and other contaminants from falling into it.
- Use a clean, long-handled ladle to spoon out water from a matka.
Can we put RO water in earthen pot?
Yes, provided you take the necessary precautions. For generations, earthen pots or matkas have been used to store water and keep it cool. Allow the water to cool naturally. Once it reaches room temperature, you can store it in a clean matka or surahi.
