Condensed Phases: Liquids and Solids
... Thus, the molar volume of a gas is about ~1000 times that of a liquid or solid. This means the molecules in a liquid or solid are much closer together, by a factor of ten, than they are in a gas. If the ratio of the gas volume to liquid volume is 1000, then the ratio of the distance between the mole ...
