As an earthen pot has minute pores within it, evaporation occurs. And since evaporation has a cooling effect, the water within the pot starts to cool

This is because of evaporation. When a liquid changes to a gaseous (or vapour) state without boiling, it is known as evaporation.
The earthen pot is made of mud and has many minute pores (extremely small holes). Through these pores that the water, placed inside the earthen pot oozes out. Now, to evaporate, the water needs to absorb heat, which will change it to vapour.
The only way the water oozing out of the earthen pot can turn to vapour is by absorbing heat from the liquid within the earthen pot and the earthen pot itself. Due to this process of continuous absorption of heat from the water inside the matka, in a few hours, this water becomes cool.
