The body will float in the water after it has drowned for a while. The body will not stay down.

Why does an egg sink in fresh water but float in salt water but stays in the middle when pour water into salt water?
Eggs, water, floating.An egg doesn't float in fresh water but since salt water is more dense than fresh water, it has a better chance of floating in the salt water. The greater buoyant force allows the egg to float in the salt water, if salty enough.More explanationAn egg sinks in fresh water but not in salt water because fresh water is not as dense. In order for something to float, the buoyant force has to be greater than or equal to the weight of the object. The buoyant force is equal to the weight of the liquid that is displaced by the object. To figure out the weight of the water displaced you multiply the density of the water by the volume and then multiply that by gravity. The density of the fresh water is less than the density of the salt water, therefore the weight of the water displaced will be greater in the case of the salt water, resulting in a greater buoyant force.The more salt in water the more bouyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea. The density of the salt water is greater than the density of the egg. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the egg doesn't float in freshwater.Did you know?A fresh egg will sink in fresh water but it will float in salty water. A rotten egg will float in fresh water.
Does Mercury float?
no, mercury is a substanable resource meaning non waterised substance so cannot float in water No, mercury is heavier than water. It can't float in water. It is actually a metal that is liquid at room temperature and for several degrees around that. That's why it's used in thermometers.
How salty does the water have to be for an egg to float?
The sea has to have at least 4 tablespoons of salt in order for an egg to float.
Is water with more salt more dense than water with less salt?
Yes, in fact, there is a lake called the Dead Sea, which has a very high salinity level, so high, that people float as if they were on a float or a raft.
Ships float submarines sink?
Wrong!!!! Ships float, and submarines also float. However, submarines have special buoyancy tanks, which are filled with sea-water, which then makes then sink. The air in these tanks is removed by a vacuum, out into compressed air cylinders. , this allows water to enter and hence the submarine sinks. To make the submarine re-surface, the compressed air in the compression tanks is blown back into the buoyancy tanks, thereby pushing out the sea-water, hence the submarine re-surfaces(floats). Remember the Archimedian Principle. 'The weight of a body immersed in a fluid is equal to the weight of the fluid displaced'. As an experiment to yourself, obtain a spring balance, an house brick and a tanks of water. Attach the brick to the spring balance, with a piece of string, and note the weight in air. Now keeping the brick attached to the spring balance lower it into the water of the water tank, and note the new less weight. The difference in the weight is the weight of the water displaced by the brick. Hence Archimedes principle and the reason why ships and submarines can float, because the displace less water.
Is mercury sink or float if you placed in sea water?
Mercury is a heavy metal, it will sink in sea water.
Will the object sink or float in water?
Whether an object will float or sink in water will depend on its volume and weight. If the weight of the displaced water is more than that of the body, the body will float. On the other hand if the weight is the displaced water is less than that of the body, the body will sink. Again if both of them are equal, the body will partially sink. Sea water contains salt. So its density is more and consequently, the weight of the sea water is more. So there is more chance of a ship to float in sea water than in river water. ADD: It depends on the density of the object. If an object is denser than water, it will sink. If it is less dense than water, it will float.
Why things float in the dead sea?
becuase there is such a high salinity that the water is too thick for anything to sink in it
How do submarines float sink and stay in the middle of the sea or ocean?
They use ballast tanks to contain sea water or air to control their depth
Why did the old island in Hawaii sink under the sea?
The islands do not float, and cannot sink. Think of the islands as being REALLY tall mountains- that start on the sea floor and go up from there. Part of the mountain is above water.
What is the density of the water the sea lions live in?
Otters can change their density to either float on the surface of the water, or sink. Therefore, their density can vary.
Where on earth you can float and not sink?
The dead sea. The level of salt is so high that it will make it very hard to sink.
Why do thing float higher in salt water the?
Due to high density of sea water things float higher in sea water.
If a sumbarine submerges what is it doing?
A submarine is a sea going vessel that is designed to run submerged or on the surface of the sea. Basically, by filling ballast tanks with sea water, the submarine will sink, and by blowing out the sea water from the ballast tanks with compressed air, the submarine will float on the surface.
Would sea water float on water?
No.
Is the Dead Sea an ocean?
The Mediterranean Sea. You can float in it. I think it's impossible to sink. It's full of salt!
Why person not float in sea water?
A person will actually float in sea water, even more easily than in fresh water because of the sea's salt content.
