When a submarine pumps water out of its inflation tanks its density decreases and floats.why does its density decrease?

It is not the matter of density. When inflation tank is filled with water then the weight of submarine is more than the weight of the displaced water. So submarine is in the sinking condition. As water is pumped out then weight of displaced water which is known as Buoyant force would be more than the weight of the submarine. So it would float.

It decreases. This is unlike most other solids.
What property will decrease if temperature increases?
Density will usually decrease in this case.
When the frequency of a waveform increases does the wavelength increase or decrease?
decreases
Does the movement of the particles increase or decrease wghile freezing?
The movement of particles decrease as temperature decreases, and vice versa. Therefore, they will decrease while freezing.
When temperature increases does ductility decreases?
no duvtility does not decrease rather it increases
When a submarine pumps water out of its floating tanks its density decrease and it floats why does its density decrease?
Density = mass / volume. If the mass decreases, the density decreases.
When a submarine pumps water out of its flotation tanks its density decreases and it floats. Why does its density decrease?
Density = mass / volume. If the mass decreases, the density decreases.
When a submarine pumps water out of its flotation tanks it and density decreased and float's does its density decrease?
Density = mass / volume. If the mass decreases, the density decreases.
When a submarine pumps water out of its floatation tank its density decreases and it floats. Why does its density decrease?
To rise again, the submarine's weight must be decreased. Air is pumped into the ballast tanks to force the water out. The buoyant force acting on the submarine now exceeds the submarine's weight. With positive buoyancy, the submarine rises. The less weight an object has the more its density decreases. Hope that kinda helps?
What happened to the economy during stagflation?
Higher rates of inflation, decrease in business productivity, high unemployment
Does the purchasing power of money decrease with inflation?
Inflation destroys the purchasing power of a paper fiat currency such as the dollar. In practical terms this means that when inflation is high the same number of dollars today will buy a smaller amount of goods or services tomorrow.Decrease. Inflation is when more dollar bills are printed. When you have more of something, the value always decreases per each of the something.
When a submarine pumps water out of its floatations tanks its density decreases and it floats Why does its density decrease?
Because the tanks are filled with air afterwards. Air has a lower density than water.
