Size dependence of (a) the average energy of a water molecule in the first solvation shell (continuous lines), , and the value of the average energy, , in the bulk (dashed lines), and (b) same for the Gibbs free energy of a water molecule. Results are at different temperatures: T* = 0.16 (red), 0.20 (blue), and 0.30 (green). Pressure is set to p* = 0.19.
