Question

Why a living person sinks ( who doesn't know how to swim) in the water while a dead body floats on it..?



No silly answers ☺

Answer 1

For a body to float in a liquid, the condition is that, it's density shall be less than the density of water. Therefore, when a body dies, the lungs get filled with water and the body sinks in water .
After some time, the tissues decompose forming gases like methane, carbon dioxide etc, hence the body becomes less dense and the body rises.

While a living body sinks due to it's density greater than the density of water.

Hope this helps!!!
