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.
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 does water kept ina earthen pot become cool during summer?
By evaporation
Why does water kept in a pot remains cold?
It doesn't, it is room temperature minus visible light heat unless in a conductive / heat absorbing container.
Why water is cold?
Not all water is cold, but if it is, that is because the H20 molicules are slowing. Most water for drinking is kept cold.

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.
Sodium is put into a large bowl of cold water?
Sodium catches fire at room temperature. So it is kept in bowl of cold water.
If you lived in an area with very cold winters should water be kept in you outdoor pool all winter Why or why not?
No, water should not be kept in your pool all winter. When it gets cold enough, the water will freeze. When water freezes, it expands. So when the water in your pool freezes and expands your pool will be ruined.
Why is the water so cold in the room of frigidarium?
The water was cold so that it would close up pores that would have been opened up by the hotter water of the tepidarium and caldarium. It was sometimes kept cold using snow.
What happens when a cold thermometer is kept in a hot tub of water?
the termometre gets warmer
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.
