Hot Air Balloon Operations
How is the operation of a hot-air balloon and that of a submarine the same?
They both vary their -buoyancy- in order to move up and down. The hot air balloon does it by varying the density of the air in the balloon, and the submarine does it by varying the amount of water that's inside the hull.

Just Cause 2: Operation Extract Hot Air Balloon
explain (the application of density in the operation of hot air balloons, and submarines)?
An object that is more dense than surroundings will sink, an object that is less dense than surroundings will float.
Thus, in a hot air balloon (an open system), the heat causes the gas to expand, and as it is not confined, the density drops and the balloon floats or rises. As it cools, the density rises and thus the balloon drops or lowers.
In a submarine (a closed system), water or ballast is pumped in pressurising the air in the tanks, increasing the density causing the submarine to sink or submerge. Then the pressure is released, the density drops and the submarine rises.
