Heya friend!
Here's your answer !
When water is poured into the earthern pot, a small part of the water poured exits through the pores on the pot and it evaporates from the surface of the pot, thus making the water in the pot cooler . For evaporation to take place, water should get converted to vapour which occurs only when there is heat in the surroundings. So water evaporates when it absorbs heat making the container cooler. When the molecules escape the liquid a vapours, the water loses heat in the form of kinetic energy of the leaving molecules.
Hope it helps!!☺

The walls of an eathen pot are porous,which leads to seepage of water. It is the main reason you will find the outside wall wet. Now the water which comes to the outside surface though seepage gets evaporated.For evaporation to happen, there is a factor called latent heat of evaporation,i.e. it must absorb some heat to change its material state from liquid to gaseous one. So it absorbs the heat from the water inside the pot to change its state. Now the water losing heat energy consequently looses temperature making it cooler than the atmospheric temperature. That is why water remains cool in an earthen pot.
