YES!!! Human density is 0.97 of 100 for water. So since we are less dense than water , we will float. Added to which nature gives us a pair of 'water wings' , they are called 'lungs'. Yes!!! you can lie on the surface of water, but because our density is slightly less than watert , most of the human organism will immerse in water, but enough is left above the surface of water, for us to breath.
Bodies sink when the lungs & stomach fill up with water. Once the stomach acids mix & begin to decompose it creates a gas that fills the stomach & lungs up like a balloon then the body will float to the surface.
Well not all organs can float, but lungs can float on water
it should have less density to float on water.
The car openings all need to be properly sealed to prevent water entry to the car body and then many cars will float. There are numerous holes and seams in the car body that are plugged and sealed but not sufficiently to prevent water entry.
The body will float in the water after it has drowned for a while. The body will not stay down.
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
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 ...
dead sperm?
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.
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.
you float cause the salt evaporates ant o2 rises
