Dead bodies float in water?

Question

a person who dont know swimming , when fell into river /ocean starts sinking initially and floats only after he is dead

Answer 1

there is a lot of hollow space in our body.....when we are alive those parts are mostly filled with gas(nitrogen probably)..when we die, all the gas moves out of the body and our weight reduces...thus we float..hope u got it!!

Answer 2

Basically, when you are alive, you float, because you have air in your lungs. If you drown, your lungs fill with water and you sink. After a few days, bacteria in the body start to produce gas from decomposition, so the body floats again.

There are other factors - if you have a lot of body fat then you may float even if your lungs are full of water. On the other hand if you go below about 60 feet deep, the water pressure is so great that it compresses the air in your lungs, and you will sink.
