$\large\bf{\underline{\red{Physics}}}$

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. If a substance's relative density is less than 1 then it is less dense than the reference; if greater than 1 then it is denser than the reference.

Answer 2

Answer: A sample of glass can be broken or adjusted to have any mass we choose, but its density will always be 2.70 g/cm3 at 20°C, so the forensic sample can be used to identify the glass bottle from which it was broken. The densities of some common pure substances are listed in the Table.
