Dead bodies float due to the gases produced during decomposition. The gases are lighter than the water, causes the body to float and to continue decomposing
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.
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
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.
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:)
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.
bacteria in the intestines produce gas, which bloats the body, making it less dense than water
There are a wide variety of factors that influence this. Bodies float due to decomposition gases trapped within it affect its buoyancy. A body sunk in cold, oxygen free water …might not decompose in such a way as to ever cause it to float.
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

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.
dead bodies can't obiously move so they lay in a straight forward position. Only straight and accurate shapes can float. if u lie straight in water (u the living one) u would …float 2 p.s- stupid question
Sort of, its the gasses produced by those bacteria that makes it float.
Rice is more dense than water , while the human body is very less dense than water
When something dies, gasses are released by the body. These gasses collect and cause the body to swell, and if the body is in the water, they cause it to float.
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.
