Density is defined as the mass per unit volume of a substance. It can be expressed as follows:
Density = mass / volume
The SI unit of density is kilograms per metre cubed.
If we hold cubes of equal volume of different solids such as wood, aluminium, lead, etc, we notice immediately that lead is heavy but wood and aluminium are light. We express this by saying that lead has a higher density than wood or aluminium.
The density of water is 1000 kg / m3 (or 1 g / cm3). The densities of some of the common substances are as follows:
Alcohol: 790 kg / m3
Gold: 19,300 kg / m3
Turpentine: 870 kg / m3
Platinum: 21,500 kg / m3
