Why the water remains cool in earthen pitchers?

The water in pitchers gets evaporated through the pores present in the pitcher body causing the by evaporation. Some heat energy is utilized during the process of evaporation. Since this energy is taken from the water itself, it leads to a lowering of temperature in the remaining amount of water present.

Why Liviving bodies doesn’t sinks in Deas Sea?

This is a very simple formula , and can be explained and understandable through the Archimedes law that states that the body with low density floats over the high density ! So the dead seas water is too much high in density due o the soluble salt in it. Dead sea having the extremely high density due to solved salt ...
