Question

Define density and specific gravity.​

Answer 1

Answer:

Relative density, or specific gravity, is the ratio of the density of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest; for gases, the reference is air at room temperature

Answer 2

$\huge \boxed{ \mathcal{ \underline \red{AnSweR:}}}$

Density is defined as the maer unit volume of substance whereas specific gravity or relative density is the ratio of the weight of certain volume of substance to the weight of an equal volume of water.
