Many gases produce in body of human. When the man die the water enter the human body and there is no way for air to diffuse out of the human body .As the gasesare lighter so they try to diffuse out of the water due to this the dead body floats on water
Gases that are lighter than the water build up in a dead body after several days, causing it to eventually float.
The body will float in the water after it has drowned for a while. The body will not stay down.
because it has so much salt in it that it enables the body to float instead of sinking in the water
The Dead Sea.
Gases build up in a decomposing body in water and makes it float, but the head remains heavy and so tends to sink just below the water level.
Dead body(s) will float in seawater [at least dead animal body(s) do]. ... visualize that once the body begins to decompose bacterial gases will cause the body to float to the surface ... imagine that body(s) which end up in deep water (thereby very cold water) do not experience bacterial decomposition as quickly and consequently with limited light and oxygen any bodies in deep/cold water decompose and are consumed more slowly without floating to the surface due to bacterial gas expansion common to warm water ...

A dead body decomposes in water as the organs & cells absorb water.The decomposed body increases in volume weight to displace more water to float. A living body cannot displace water as the volume and tends to sink in water.
The Dead Sea is much saltier than other seas. The dissolved salt increases the density of the water, making it easier to float on.
The higher the salt content of seawater, the more buoyant the water is. And the Dead Sea has the highest salt content of any body of water in the world.
you float cause the salt evaporates ant o2 rises
After death, the organisms/bacteria within the body will metabolise and multiply, producing lots of gas in the process. Most of this gas is unable to escape, so the body expand and float from all of the gasses present. The body will then sink again once it has decayed enough to allow the gasses to escape.
Dead bodies float on water much the same way living bodies do. And yes, living bodies do float on water. But if you panic and exhale, you will sink. IF you stay calm and keep your lungs inflated you will float. This is because of density. Anything less dense than water floats, and anything more dense than water sinks. Our human bodies have a density close to that of water and we WILL float if we keep our chest expanded and lungs filled with air. When people drown, their lungs are full of water and they sink. After a number of hours, up to a few days, gases from decomposition trapped inside their body make them buoyant and they will float. Then carrion eaters, blow flies, and other flesh eating creatures will puncture through their tissues, releasing the trapped gases, and causing them to sink again.
