selected relative densities
selected relative densities Relative density (or specific gravity) is the density (at 20°C/68°F) of a solid or liquid relative to (divided by) the maximum density of water (at 4°C/39.2°F). The relative density of a gas is its density divided by the density of hydrogen at the same pressure and temperature.
