Using an HF/6-311G level of calculation, we have analyzed the meaning of the density of states (DOS) for a single molecule of water (H2O).
The density varies with temperature, but not linearly: as the temperature increases, the density rises to a peak at 3.98 °C (39.16 °F) and then decreases; the initial increase is unusual because most liquids undergo thermal expansion so that the density only decreases as a function of temperature.
