at a given pressure (see PRESSURE; TEMPERATURE).
The freezing point of a pure (unmixed) liquid is essentially the same as
the melting point of the same substance in its solid form and may be
regarded as the temperature at which the solid and liquid states of the
substance are in equilibrium. If heat is applied to a mixture of liquid and
solid substance at its freezing point, the temperature of the substance
remains constant until it has become completely liquefied, because the heat
is absorbed not in warming the substance but in providing the latent heat
of fusi....
