Descripción
Water is denser than air. A submarine sinks and surfaces because of a mechanism that allows the displacement of water and air. When water is forced into a chamber, the submarine sinks. When the water is forced out of the chamber by air, the submarine surfaces. To keep the submarine at a constant level, the chamber maintains a balance of air and water. In this investigation, a model of a submarine is built to simulate the buoyancy and displacement of water and air.
