Answer:
Well, the densities of the condensed phases, solids, and liquids, are more or less constant...
Explanation:
...and not subject to change. The condensed phases are largely incompressible. On the other hand, the density of the gaseous phase is highly variable...and is a state function of temperature, pressure, volume, and amount of gas... And gaseous phases should have an intrinsically low density in comparison to solid and liquid phases...
