Density—Sink and Float for Solids Chapter 3 Density

The mass of the steel is the same but the big increase in volume makes the density of the bowl less than the density of water so the bowl floats. This is the same reason why a steel ship is able to float. The material is shaped in such a way so that the density of the ship is less than the density of water.

Lab 8 Buoyancy and Archimedes Principle

Specific gravity, S, is often used to characterize an object's density with respect to the density of water. We may express this as S = ρ ρ f (10) In all cases examined here, the fluid is assumed to be pure water ( ρ f ≈1.0 g cm 3). Notice that S is a unit-less quantity, since the units of the densities cancel. Also, a body's
