Origin: [L. densitas; cf. F. densit.]
The mass density or density of a material is its mass per unit volume. The symbol most often used for density is ρ. Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume. In some cases, density is also defined as its weight per unit volume, although this quantity is more properly called specific weight. Different materials usually have different densities, and density may be relevant to buoyancy, purity and packaging. Osmium and iridium are the densest known elements at standard conditions for temperature and pressure but certain chemical compounds may be denser. Less dense fluids float on more dense fluids if they do not mix. This concept can be extended, with some care, to less dense solids floating on more dense fluids. If the average density of an object is less than water it will float in water and if it is more than water it will sink in water. Density is sometimes expressed by the dimensionless quantity "specific gravity" or "relative density", i.e. the ratio of the density of the material to that of a standard material, usually water. Thus a specific gravity less than one means that the substance floats in water.
