Question

Why does a human body float like a cork in the dead Sea?

Answer 1

As we know dead sea is the most saltiest sea of the world (density = 1.4 g/cm³) Due to it's high salt contents the density of human body (1.16 g/cm³) becomes lower than the density of dead sea and it floats like cork on water or egg on salty water.

I hope this will help you.

Answer 2

Dead sea is not actually a sea .it is actually a salt lake lying on the borders of Jordan in the East and Israel in the West .it is the lowest point on the surface of the Earth .
Due to presence of high quantities of salt animals are unable to survive in this sea . Anyone can easily float for hours on the surface of the dead sea without any danger on so sinking because of natural buoyancy . The buoyancy is caused due to the high salinity present in the dead sea.salinity is caused due to the accumulation of salt that flows in different water bodies and due to the lack of a drainage system the salt gets deposited in the waters of the dead sea.and when the temperature is high the water in the dead sea gets evaporated but it leaves the salt behind. And due to this phenomenal the density becomes higher than normal water. Creating a greater upward thrust on a body which is floating.this is the reason y a human body float like a cork in the dead Sea
