School Relative Density Bottle

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.
Specific gravity usually means relative density with respect to water.
The term "relative density" is often preferred in scientific usage. It is defined as a ratio of density of particular substance with that of water.
