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.

What objects will float sink then float?

Why does a submarine can sink and float in water?
because the submarine has the water tank.when the tank is filled then submarine sink in the water.and when the tank is empty then submarine float in water.
How does a submarine relate to astronomy?
the ability of the submarine to float
How can a submarine float and which force is acting on it?
The buoyant force keeps a submarine afloat.
Does a submarine sink or float?
both. they are able to control it
How do you make a plastic bottle submarine float then sink and float?
put water in to let it sink... then put air into it to let it float...
How do submarines float and sink in water?
a submarine has a water tank. when the tank is filled then submarine sink in the water. and when the tank is empty then submarine float in water. use the formula density= mass / volume as mass increases(when the tank is full of water), the density of the submarine increases and it submerge into the water and vice versa.
The density of a submerged submarine is about the same as the density of?
The dnsity of a submerged submarine is the same as the density of the water if the density of the submarine was grater it will sink, if the density was less it would float.
What can go across the Atlantic oceon?
anything that can float on water, unless its a submarine
What is a landmine and a submarine mine?
Landmines are positioned under earth and leaves. A mine for a submarine hangs in the water below the water surface, or is ejected from a ship's deck to float down to the depth of the submarine.
How does a submarine works that floats then sinks and then again floats?
A submarine sinks as it fills its' ballast tanks with water. Then it uses pressurized air to empty them and float again.
What is a sea going vessel?
its anything that can float in sea like a submarine,ship, yacht etc
