Density is the mass of any material per unit volume. Gases always have much lower density than the condensed phases. Most materials have a lower density of the liquid than the solid but this isn't always true. Water has a higher density in the liquid state than the solid, so ice cubes float.
Within a particular phase, how does the density depend on temperature?
Remember that temperature is related to the average kinetic energy of the atoms or molecules within the substance. We know that, for gases, the volume is directly proportional to temperature by the equation PV=nRT.
