title: Thermodynamics of extensive interfaces between rigid, apolar walls and water.
abstract: A simple set of equations is proposed to govern the relations between the thermodynamic potentials in rigid, apolar wall-water systems, which is found to be consistent with the data for two systems: alkane plate-SPC/E water [R. Zangi and B. J. Berne, J. Phys. Chem. B 112(29), 8634-8644 (2008)] and graphene plate-TIP4P/Ew water [R. Zangi, J. Phys. Chem. B 115, 2303-2311 (2011)]. These data exhibit exact compensation of enthalpy and entropy for the water-water interactions. Surface tension of the free water surface is the invariant excess free energy per unit area for the water phase in these wall-water systems at thermodynamic equilibrium.
