Submarines have positioned along the outer hull, ballast tanks. These tanks are filled with sea water to cause the submarine to reach neutral displacement, and help the boat submerge. Additionally, at the bow are positioned moveable "wings" or bow planes. When the bow planes are pointed downward, and the screws (propellers) are turning, the force of the water against the planes pushes the bow downward, pulling the boat deeper into the water.
The reverse is true as well. When the Captain wants to raise the boat, he orders the ballast tanks to be emptied, or blown for a fast rise in the event of emergencies. Pumps evacuate the water and compressed air is pumped into the tanks. This lowers the displacement. With the bow planes pointed upward, the screws push the boat upward, and it surfaces.

When water fills a submarine's flotation tanks the overall density of the submarine will...?
The density will rise and submerge the submarine.
When water fills a submarines flotations tanks the overall density of the submarine?
The density will rise and submerge the submarine.
What does a submarine alter to rise and fall in water?
A submarine alters its buoyancy to rise and fall in water by adjusting the amount of water in its ballast tanks. When the tanks are filled with water, the submarine becomes heavier and sinks; when air is pumped into the tanks, the submarine becomes lighter and rises. This process allows the submarine to control its depth in the water column effectively.
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.
What is the function of the ballast tanks on a submarine?
To change the buoyancy of the boat and allow it to rise and sink in the water.
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 does change in buoyancy affect the function of a submarine?
A change in buoyancy affects a submarine's ability to rise and sink in the water. By adjusting the amount of water in its ballast tanks, the submarine can control its buoyancy and depth in the water. This is essential for navigating through different depths and maintaining stability.
What gas is used for a submarine to rise up?
The same gas as the Air we breath. (Mostly Nitrogen, Oxygen and Argon)
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.
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.
What are volcanoes that do not rise above sea level?
Volcanoes that are underwater, known as submarine volcanoes. The deepest one is the Submarine 1922 in the Celebes Sea near the Sanghie Islands of Indonesia, and it is 16,000 feet (5,000 meters) below sea level.
When the air in the submarines huge air tanks is decompressed what does the submarine do?
When the air in a submarine's huge air tanks is decompressed, the submarine typically ascends to the surface. This is because the decrease in air pressure allows the buoyancy of the submarine to increase, causing it to rise. Submarines use this method to control their depth and ensure safe surfacing or to adjust their buoyancy as needed during operations.
