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.


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 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.


When a submarine pumps water out of its floatations tanks it 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.


When a submarine pumps water out of its floatation 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.


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

When a submarine pumps water out of its inflation tanks, it essentially removes a dense substance (water) and replaces it with a less dense substance (air). This change in density causes the overall density of the submarine to decrease, making it less dense than the surrounding water and allowing it to float.


When a submarine pumps water out of its floatation tank its density decreases and it floats. Why does its density decrease?

The submarine's density decreases when water is pumped out of its floatation tank because the overall volume of the submarine remains the same while the mass decreases. This leads to a lower density, allowing the submarine to float.


When a submarine pumps water out of its floatation tanks its density decreases and it floats?

Yes, when a submarine boat pumps water out of its flotation (not floatation) tanks, the submarine should rise.


When a submarine pumps water out of its floatation tank its density decreases and it floats why?

because of density


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.
