Density

The density of a material is defined as its mass per unit volume:
Different materials usually have different densities, so density is an important concept regarding buoyancy, metal purity and packaging.
In some cases density is expressed as the dimensionless quantities specific gravity or relative density, in which case it is expressed in multiples of the density of some other standard material, usually water or air.
Density is a characteristic of a substance; mass and volume are not. Mass and volume vary with size but density will remain constant.Temperature will affect the density of a substance and the temperature at which density for that substance was determined is usually reported along with the density value.
