how submarine works
1. when a submarine floats on the surface of the water, it's like any other metal boat, it is filled with enough air to make it float
2. tanks inside the submarine have air in them when the submarine is at the surface. to make the submarine float just below the surface, some of the air is taken out and the tanks are partly filled with water. this combination of the submarine, the water and air has about the same density as water.
3. the submarine can dive to the bottom by squeezing air in its tanks into smaller tanks. because the air volume is now smaller, it's density is greater. the original tanks are then filled with water, making the submarine denser than water. to allow the submarine to return to the surface, water is pumped out of the tanks. air is allowed to expand back into them, making the submarine less dense than water. it is buoyed up and rises to the surface
