Cavity formation chemical potentials and water reorganization energies and are plotted as a function of cavity radius and temperature . The points are simulation results and the curves are C-EOS predictions (see text for details).
The cavity formation entropies and (above) and three fundamental contributions to (below) are plotted as a function cavity radius at several temperatures (see text for details).
The thermodynamic signatures of hydrophobic dewetting are evaluated by comparing the thermodynamics of cavity formation in water and a hard-sphere reference fluid [with and ]. The agreement between the calculated (curves) and simulated (points) cavity chemical potentials up to cavities of radius is a significant test of the analytical strategy used to derive the C-EOS. The strong temperature and cavity size dependencies of imply that the critical length scale for hydrophobic dewetting (which is approximately equal to the cavity radius at which crosses 0) is a strong function of temperature.
Experimental hydration thermodynamics data for argon and xenon at both constant pressure and constant volume (points) are compared with GvdW1 predictions (solid curves) and used to extract fundamental thermodynamic quantities which are typically not experimentally accessible (dashed curves). Comparable results have also been obtained for , , , and (see text and Tables I and II for details).
