  We use molecular simulation to compute the thermodynamic properties of 7
rigid models for water (SPC/E, TIP3P, TIP4P, TIP4P/2005, TIP4P/Ew, TIP5P, OPC)
over a wide range of temperature and pressure. Carrying out Expanded
Wang-Landau simulations, we obtain a high accuracy estimate for the
grand-canonical partition function which, in turn, provides access to all
properties, including the free energy and entropy, both at the vapor-liquid
coexistence and for compressed water. The results at coexistence highlight the
close connection between the behavior of the statistical functions and the
thermodynamic properties. They show that the subgroup
(SPC/E,TIP4P/2005,TIP4P/Ew) provides the most accurate account of the
vapor-liquid equilibrium properties. For compressed water, the comparison of
the simulation results to the experimental data establishes that the TIP4P/Ew
model performs best among the 7 models considered here, and captures the
experimental trends for the dependence of entropy and molar Gibbs free energy
on pressure.
