Answer 1

Answer:

It is the ratio of the density of a substance to the density of a standard, usually water for a liquid or solid, and air for a gas.

Answer 2

Explanation:

specific gravity

specific gravityRelative 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. ... If the reference material is water, then a substance with a relative density (or specific gravity) less than 1 will float in water.
