We
can also calculate a density for substances in the liquid
state at room temperature.
For all but one substance, the density of the solid state
is greater than for the liquid state. This is because the
particles move slightly closer together during
freezing. For example, we have seen this for wax and salt:
Water is the exception. The particles move slightly
further apart when it freezes.
