The density is the mass per unit volume of that substance.
The unit of density is the kilogram per cubic metre.
The symbol of density is the Greek letter ρ.
Relative density (or specific gravity) is the ratio of the density of a substance at a stated temperature to the density of water at 4 degrees Celsius.
Lower density fluid float above higher density fluid.
