The average density of a submerged submarine is about that of the water that surrounds it. It is said to have neutral buoyancy. But the average density of a floating submarine is less than the density of water, otherwise it would not float. (It could be argued that the density of a submarine is constant and that its characteristics as regards buoyancy are manipulated.)
A submarine has "empty spaces" inside the pressure hull. That's where the equipment that makes a submarine work is (along with the crew). When a boat (the submarine sailor's term for his vessel) is submerged, the whole volume of the vessel displaces a likevolume of water. This is true, except that the main ballast tanks are full of water; they have no air in them. The submarine is set up to be neutrally buoyant when it's under water. That way no "effort" or "energy" is spent trying to keep the boat from sinking or floating to the surface.
When a submarine is on the surface and the ballast tanks are filled with air, the whole boat floats. The extra air that has been put into the main ballast tanks has displaced the water that was in them when the boat was submerged. This extra buoyancy allows the boat to float and operate on the surface.

The density of a submerged submarine is about the same as the density of?
The dnsity of a submerged submarine is the same as the density of the water if the density of the submarine was grater it will sink, if the density was less it would float.
Does a floating object weigh more when underwater?
Statistically it weighs the same, but it feels less when it is submerged underwater.
What effect does the density of liquid have on the buoyancy of an object?
An object with lower density than the liquid will float, one with more density will sink. Anything with the same density will stay at the depth where it is placed. If it is placed half submerged it would sink until submerged.
Does a weighted air filled balloon with the same density as water float or sink?
Neither, it just stays submerged, provided its density stays the same as the water around.
If an object has the same density as the fluid it is submerged in the object will always?
Will always float with the top surface level with the water
When a submarine pumps water out of its floatation tanks its density decreases and it floats. why its density decreases?
The water is replaced with air which is not as heavy as water for the same volume.
When a submarine pumps water out of its flotations tanks its density decreases and it float. Why does its density decrease?
Density is weight divided by volume. Since the size of the hull stays the same, when the weight of the water is removed, the volume of the hull stays the same and the density is reduced.
Is the magnitude of buoyancy experienced by the objects constant for a particular liquid?
It depends on the objects' volume. Different objects that have the same volume, if submerged, experience the same buoyancy. The buoyancy is equal to the weight of the displaced liquit; in other words, volume (of submerged object, or of the submerged part) x density of the liquid x gravity.
What can you do with density?
Density is the measure of pounds per square inch it would be important if you designed tanks because you would need to know what density of the tanks armor it would need to be same as in a submarine.
Is the bouyant force of water proportional to its depth?
No. Water is incompressible. Buoyancy is determined by density, and being incompressible the density stays the same. Once an object is submerged there's no more buoyancy to be generated.
Can submarines go from New York to Chicago?
Yes they can. They would follow the same route freighters use. But they would run on the surface. It would be far to dangerous for a submarine to make the trip submerged.
A cork is floating in salty water As more salt is added to the water to increase its density the cork will?
it float at the same level in water.
