Why the dead body float on water?
Gases that are lighter than the water build up in a dead body after several days, causing it to eventually float.

When the fish dies,its gills will push out air from the body.The moving air's force pushes the fish deeper into the water.A few minutes later, it will float up due to the air …in the air bladder of the fish. That's the answer for the SEE programme Q9! From one of 6R8's students
You are still floating because you have oxygen in your lungs. But if you drowned from a large body of water like the sea, you will float because you have consumed large amount…s of water. And one more thing, we have this thing called buoyancy. Ah huh. :]
A cadaver in the water starts to sink as soon as the air in its lungs is replaced with water. Once submerged, the body stays underwater until the bacteria in the gut and chest… cavity produce enough gas -- methane, hydrogen sulfide, and carbon dioxide -- to float it to the surface like a balloon. (The buildup of methane, hydrogen sulfide, and other gases can take days or weeks, depending on a number of factors.) At first, not all parts of the body inflate the same amount: The torso, which contains the most bacteria, bloats more than the head and limbs. The most buoyant body parts rise first, leaving the head and limbs to drag behind the chest and abdomen. Since arms, legs, and the head can only drape forward from the body, corpses tend to rotate such that the torso floats facedown, with arms and legs hanging beneath it.
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.
There are several factors involved in the floating sinking of a body (alive or dead): Live body People tend to have positive buoyancy when alive as their lungs are full of… air. This makes a persons total density less than that of water. This made obvious by the fact that scuba divers usually wear lead weights . A persons physical makeup can also influence this lower density - more fat, less overall density. External to the body itself some folks carry a great deal of ballast (camera, coins, tool belts, heavy boots, outboard motor accidentally caught in clothing) which increase their average density and they sink. Dead body A dead body (at firat) floats or sinks the same as when the person was alive as nothing changed - density wise. However the lungs may fill with water either b a last gasp inhales water or by puncture wounds to the lungs (e.g. a car accident) This increases the density and the body sinks. In crime movies the boy often is equipped with "concrete overshoes" or a convenient chunk of scrap iron to weigh them down, Then comes the miracle of decomposition. Microbes eating the intestinal contents generate gas which is held in the intestines. This increase the buoyancy and the body rises up through the water. As time goes on, leaks appear in the tissue holding the gases in (fish, crabs, wear and tear) and the gas escapes, increasing the average density and the body sinks for the final time.
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.
That depends upon a large number of factors. How warm is the water? Is the water still or is it moving? Bodies are usually heavier than water, so when the lungs are fill…ed with water the body sinks. Decomposition begins to occur, and gasses released from that trapped inside the body cause it to float. Water that is sufficiently cold may act to prevent decomposition gasses from floating the corpse. Also, puncture wounds may release trapped gasses. Sometimes clothing may snag on something underwater, keeping the body down. Once the corpse floats scavengers such as carrion birds or insects may perforate the flesh, releasing the gasses that cause the body to sink again. This can take anywhere from a few hours to a few days, again depending upon a wide variety of circumstances.
A body floats due to the gases left in the body, once the gases dissipate the body sinks until it produces more gas to float.
The organs in the lower body decay and fill with gas from the decay, which makes it float. The head and skull have no room for gas because they're filled with the brain, so th…ey stay heavy and sink downward. courtesy:zaid
Because...our body has density.The amount of mass in a certain volume of matter is a property called density...the density of our body is less than the water that is why… we float on water.But it's just a little less!
you float cause the salt evaporates ant o2 rises
the human body can float on water because you are holding your breath of course!!!Yes. Basically, air floats on water. If you breath in a lot of air, then you will float. Also…, fat floats, and so humans with some fat on their bodies would float better than humans without fat.
Well both a dead body and living one floats on top of water. But the more you panic, the faster you will sink. If you were to stay calm and relax, you will have no problem wit…h floating on top of water.... this is because of density. Anything less dense than water will float and anything more dense than water will sink. Our bodies(YOU CAN BE 600LBS) have a density less than water....so we will definitely float. so if u find yourself "drowning", just stay calm and let human nature take it's course:)
It floats because after death, the bacteria in the body continue to feed off the host (the body) as the bacteria feeds, and the body continues to decompose, it creates gases t…hat are trapped in the body making the body float. After the body decomposes enough to create openings for the gas to escape the body sinks. This is why someone sinks when they first drown. After they sink, the body starts the decomposition process, creates gases, and floats to the surface.
No. The Dead Sea is called that because it is so salty that nothing can live in it.
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 t…hey try to diffuse out of the water due to this the dead body floats on water
