. The Titanic lies 2.5 miles below the surface of the Atlantic. The pressure at that depth is approximately 3 tons per square inch. In 1996 a section of the hull was floated to the surface using large buoyancy balloons filled with diesel. Diesel in less dense than water but considerably more dense than air. Why was diesel used instead of air in the buoyancy balloons? Explain.
