Steel is a popularmaterialfor the construction of cruise ships and submarines. In average, its density is close to 7.85 g/mL. When compare to the density of water (1.00 g/mL, both densities determined at the same temperature), it should be expected that steeldoes not flow in water. However, cruise ships float in water, suggesting their density is less than that of water, while submarines sink, suggesting their density is greater than that of water. However, they are built using the same material, steel, as the principal building material. Explain, using the concept of density, the observed behavior.
