Where might the air come from to replace the water that is pumped out of a submarines s ballast tanks?
The air to replace the water in a submarine's ballast tanks typically comes from high-pressure air banks stored onboard the submarine. These air banks are filled with compressed air from the submarine's air compressors and are used to control the submarine's buoyancy by adjusting the amount of air in the ballast tanks.
Why does a submarine can sink and float in water?
A submarine can sink and float in water because it has ballast tanks that can be filled with water to make it sink and with air to make it float. By adjusting the amount of water and air in the ballast tanks, the submarine can control its buoyancy and stay submerged at a desired depth or rise back to the surface.
Why can a submarine sink and float in sea water?
A submarine has "ballast tanks" which can be filled with water to make the vessel heavier (total density greater) than water and dive to required depth. These ballast tanks can also be filled with air (compressed air is kept on board for this) to make the vessel lighter and rise to the surface
What does a submarine rise when its volume is increased?
When a submarine's volume is increased (e.g. by filling its ballast tanks with air), it becomes less dense than the surrounding water, causing it to rise to the surface. This process is known as positive buoyancy.
How can a submarine control its sinking and floating?
A submarine can control its sinking by adjusting the amount of water inside its ballast tanks. Adding water makes the submarine heavier and causes it to sink, while pumping water out makes it lighter and allows it to float to the surface. The submarine also uses its diving planes and rudder to help control its depth and orientation underwater.

How does a submarine float?
It floats and sink by changing its buoyancy. The primary method of controling buoyancy is the ballast tanks. The air is let out of them and is displaced by water. This gives the submarine negative buoyancy, which will get the submarine to submerge. By blowing or pumping air into those ballast tanks, the submarine becomes buoyant and rises to the surface.

How is the descend and the ascend of a submarine controlled?
By pumping water or air into the ballast tanks.
How does a submarine work?
A submarine has tanks that are called ballast tanks. When these tanks are flooded with sea water, the submarine sinks because the sub weighs more than the water it displaces. To rise again, the sub reduces its weight by pushing compressed air into the ballast tanks. The air forces the sea water out and sub returns to the surface. It maneuvers using its rudder and planes. A link is provided.
How do fluids help ballast chambers on a submarine?
A submarine actually controls its weight by allowing water to enter or exit hollow chambers in its hull. These chambers are called ballast tanks. Ballast is anything carried in a ship to give stability. When water is allowed to flood into a submarine's ballast tanks, the weight of the submarine increases. When this increased weight exceeds the submarine's buoyancy, the submarine will sink. To allow the submarine to rise, air is pumped into the ballast tanks. The air forces out the water, reducing the weight of the submarine. The submarine then becomes lighter, buoyancy increases, and it floats to the surface. A submarine can also be made to "float" underwater at any depth by adjusting the amount of water weight in its ballast tanks.
How do people in a submarine get air?
The submarine has scrubbers. They remove carbon dioxide from the air and break it down to release the oxygen back into the air. There are also a few tanks to supplement the oxygen content if necessary.
How submarine caused to submerge without use propulsion propeller and fins?
A submarine can submerge by filling ballast and trimmer tanks with sea water. The additional weight will take the submarine down. To resurface, the submarine will blow the sea water out of the tanks using compressed air. The air in the tanks make the submarine buoyant, so it rises and floats on the surface. Though a stationary submarine can submerge in this way, it usually submerges going forward and using diving plane (fins) to steepen the dive, so getting under the surface faster.
When a submarine pumps water out of its floatation tanks its density decreases and it floats. why does its density decreases?
Because the tanks are filled with air afterwards. Air has a lower density than water.
