- • Density: In both solids and liquids, the molecules are held very closely together and therefore their densities are about the same. In gases, there is space between the molecules. • Molecular movement and order: The molecules in solids are arranged in a regular pattern that does not allow for diffusion, although does allow for vibrations. The arrangement of molecules in a liquid, although not completely random, is not completely fixed. Molecules in a gas are randomly arranged and move very quickly. Gases diffuse quickly in comparison to liquids. Compressibility and thermal expansion: Since the molecules in solids and liquids are already very close together, applying pressure does not greatly affect the volume. In contrast, the space between gas molecules allows for a great deal of compressibility. Although temperature changes will cause slight variations in the volume of a solid or liquid, those variations are negligible compared to the thermal expansion of a gas.
