• Specific gravity refers to the ratio of the density of an object and the reference material.
• Furthermore, the specific gravity can tell us if the object will sink or float in reference material.
• Besides, the reference material is water that always has a density of 1 gram per cubic centimeter or 1 gram per millimeter.

Answer 2

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. ... A substance with a relative density greater than 1 will sink.

The specific gravity of an object is the ratio between the density of an object to a reference liquid. ... The specific gravity has no units. If the specific gravity has a value of greater than one, then the object sinks in water and if it is less than one, then the object floats in water.
