Gases typically have exceptionally low densities.


#"Density, "rho="Mass"/"Volume"#. It is well-known that a gas will uniformly occupy (i.e. expand to fill evenly) whatever volume is available to it.

On the other hand, solids and liquids, condensed phases, are high density materials where #rho# is relatively constant.
