Earthen pot has tiny pores on its surface. The water oozes out from these pores. It then evaporates taking energy known as "latent heat" from the pot. Thus, the temperature of the water inside decreases. This process goes on and this is the reason why the water in earthen pot is cooled faster.
this is because the earthern pot is made up of mud. the mud has pores in it.
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.
Nuclear Pores
Water alone cannot enter your pores because it isn't dense enough to go inside and clean your pores. Soap is used to make water dense enough to enter the pores and clean them, making you a lot more cleaner.
Nucleus Pores
Stomatal pores
Nucleus is enclosed in double walled nuclear membrane. Nuclear membrane at certain distance have pores in them which are called nuclear pores. Nuclear pores are very selectively permeable.
Cell membrane
Due to capillarity water leaks through tiny pores of earth pots.Midun.M
Allow materials to enter and leave the sponge
Pores called stomata, which open and close by guard cells.
