I cannot for the life of me remember how many air flasks are located fore and how many aft, but they are located outside of the pressure hull inside the ballast tanks.

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
How can a submarine control its sinking and floating?
A submarine can descend or rise by changing its overall density relative to the water around it. It does this by filling its ballast tanks either with water (increasing its density) or with air (decreasing its density). Decreasing the amount of water in its ballast tanks by replacing it with air lowers the total mass of the submarine; this decreases its density. Compressed air from storage is vented into the tanks, pushing the water out the valves underneath. The ballast tanks full of air make the submarine less dense, so it rises. To descend, the bottom valves allow water to enter the ballast tanks, and the air escapes from valves on top; as the tanks fill with water, the sub again becomes more dense relative to the water around it, so it descends.
What happens to the buoyant force of a submerged submarine when water is taken into its tanks and it dives?
Unless the flooding and buoyancy was controlled, the submarine would continue to dive into the depths, possibly to be crushed by the great pressure of water.
What does a submarine rise when its volume is increased?
Because submarines need air.
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.
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.
