A human body typically sinks in sea water after drowning due to the increase in density caused by water entering the lungs. However, factors such as body composition and post-mortem changes can also influence whether a body floats or sinks.

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.
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.
How salty does the water have to be for an egg to float?
The water needs to be very salty for an egg to float. Typically, the water needs to have a salinity level of around 10-12% for an egg to float. This is much higher than the salinity of most oceans.
Ships float submarines sink?
Ships are designed with a hull that displaces enough water to keep them afloat, while submarines are designed to control their buoyancy and dive underwater by filling ballast tanks with water. This allows submarines to dynamically adjust their buoyancy and sink beneath the water's surface.
Does calcite float on water?
floating is a phenomena that is dependent of many factors including;density and base area.thus,looking at the density of calcite (approximately 2.7g/cc) it is greater than that of liquid water (1g/cc),hence calcite cannot float.nevertheless,in large body of water (sea,ocean) a block or pieces of calcite rock is bound to float due to surface area contrast.
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 sink or float in water depends on its density compared to the density of water. If the object is less dense than water, it will float. If it is more dense than water, it will sink. If the object's density is equal to that of water, it will be neutrally buoyant and will remain suspended in the water.
Will Asphalt sink or float in sea water?
Asphalt, being denser than water, will sink when placed in sea water. This is because the density of asphalt is about 1.36 g/cm³, while sea water has a density of around 1.025 g/cm³.
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.
Is asphalt sink or float if you placed in sea water?
Asphalt is less dense than water, so it will float on the surface of seawater. This is because asphalt is a petroleum-based material that is made up of hydrocarbons, which are lighter than water.
What body of water that is so salty that you can not sink?
The Dead Sea is the body of water known for its high salinity levels, which make it nearly impossible to sink. The dense salt content creates greater buoyancy that allows individuals to float easily on the surface.
What property causes an object to float in salt waterr but sink in fresh water?
The property that causes an object to float in saltwater but sink in freshwater is density. Saltwater is denser than freshwater due to the dissolved salts, so objects that are less dense than saltwater will float in it but sink in freshwater.
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.
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.
