Temperature Effects on Density

Temperature Effects on Density Density 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.
