why water kept in an earthern pot cools in summer?

Answer 1

Because the earthern pot has pores in it . By which some water droplets comes out & evapourate. During evapouration some heat is absorbed from the pot .
Hence the pot cools down & the water also.

Answer 2

The earthen pots have pores in them. This allows evaporation. This will reduce the amount of heat contained in the water. This is the reason for the cooling effect.

Answer 3

Evaporation cools in two ways. First, it carries off the heat of vaporization (2261.11 joules per gram of water).

The second is more intriguing. How can liquid water turn to vapor if it is not at 100 degrees C? In any fluid, some of the molecules will be more energetic than others. It's the average kinetic energy of the molecules that we call the "termperature" of the fluid. In water, some of the molecules are energetic enough (have a high enough "temperature") to escape. Since the high-energy molecules escape, they leave behind the less energetic, cooler, molecules, and lower the average temperature of the water.

Answer 4

The water seeps into the pores of the pot and reaches the surface where it evaporates. This carries off energy from the water inside thus lowering its temperature.

Answer 5

Evaporation cools the water. The water oozing out of the pot gets evaporated. While this evaporation occurs, water inside the pot becomes cold; this principle is called evaporate cooling.

Answer 6

in the earthen pot there are small pores. when water in the pores gets evaporated it takes away all the heat of the water and thus keeping it cool.

Answer 7

earthen pots has small pores , from which water rinses and due to hot waves in summers it cool the earthen pots, that way the water keep cool in summer
