The computed thermodynamic quantities for metal-water interface formation are listed in Table . Overall, the entropy of water molecules in the water film is increased compared to the calculated bulk value of 0.55 meV/K. This is due to the increased DoS at the low-frequency range as shown in Figure . All the studied interfaces have positive free energies of formation with respect to the bulk references; correspond-ingly, γ sl (F) > 0. Rh and Pt exhibit the highest surface tensions, Pd and Pd-Au have intermediate values similar to each other, while Au and Ag form the pair of lowest values. The same energetic ordering is observed for γ sl (E). As both γ sl (E) and γ sl (F) contain energetic contributions from the cleavage as well as solvation of a metal surface, a good correlation between them and the solid-vacuum interfacial energies 90 is expected and observed; the metals with the highest γ sv also have the highest γ sl . The data also show that the magnitude of the entropy of the interface formation varies from one metal to another. For instance, on Pd the entropy contribution to γ sl (F) is about 25 % of the total free energy while on Rh and Pt the entropy contribution is less than 3 %. For Au and Ag the entropy contributions to the surface tension are about 7 % and 15 %, respectively.
