Why a dead body first sink and then float over the surface of water?

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.

∙ 13y agoThe body is mostly water, fats, bone, and tissue. This will cause the body to sink. When it starts to deteriorate, the decomposing organic matter inside the body will create gases which are trapped inside the body, along with the bloating from being submerged in the water will cause it to rise to the surface again.

∙ 13y agoYes, especially in salt water. The dead human body will fill up with gas and float. After the Titanic sank, a lot of bodies were found floating on the surface for many days afterward. When someone is murdered, the murderer will often put on lot of weights on the person, such as metal chains, or cement, to make sure the body does not float back up to the surface.

∙ 9y agoDead bodies float due to an accumulation of gases. These gases are a by-product of decomposition. The gases are lighter than the water and buoy the body to the surface.

Why taking a deep breath helps you float in water?
it help because the more air you have the more your body can suspend on top of the water surface
Do humans float if they lay flat on the surface of the water?
Personally, I float if I inhale; but I sink if I exhale. Your results may vary - for example, depending on the amount of body fat.
Do humans float on water?
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.
Why do you float back to the top when you dive under water in your swimming pool?
Because your body is less dense than the water. More dense bodies go down, in fact you don't float back to the top, the water falls down not leaving room for your body but up to the surface.
What conditions must be met in terms of density of a body for it to float submerged in water?
A body whose total density is greater than that of water will sink in water;that is, if it's not supported, it will continuously drift lower.A body whose total density is less than that of water will float in water; that is,it will sink only partially, and will then remain on the surface and sink no lower.A body whose total density is exactly equal to that of water will have "neutral buoyancy",and will "float submerged" so to speak. That is, none of it will remain above the surface,but once submerged, it will neither rise nor sink further, but will maintain the depth at whichit is placed.
What would happen to a fresh water cell if placed into salt-water?
die..and its body will float on the surface
What body of water in the middle east is so salty that its easy to float on the surface?
The Red Sea a
How does salty water help you float?
The density of ocean (sea) water is approximatley 1.025; the density of the human body is approximately 1.00; less dense objects float on top of or near the surface of denser liquids. The saltier the water or the more body fat you have (body mass index), the better you float. Cheers Malcolm
Why do marine mammals float?
Not all marine mammals float, but the ones that do float because the body of the animal is sitting on the surface of the water and that makes the pressure of the body of the animal float because the body is rising from all the pressure. Hope this helped -stupid factory

Will dead body float in seawater?
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 ...
Why man floats in the surface of water after death?
As the body decomposes, it releases gasses from the inside almost like a ballooning effect causing the body to "float".

Do float or sink in sea water after you have drowned?
The body will float in the water after it has drowned for a while. The body will not stay down.
