Fig. 5: Isobaric-isothermal Monte-Carlo simulation results.
From: Nanoscale thermodynamics needs the concept of a disjoining chemical potential
Evidence for the hysteresis in the compression-expansion isotherm for an ideal gas confined in a slit pore (computational conditions and details are given below in Methods section). Repulsive square-well gas-wall potential (\(\varepsilon \, < \, 0\)) at a reduced temperature, \(T=0.9525\left|\varepsilon \right|{{k}_{B}}^{-1}\,({e}^{\beta \varepsilon }=0.35)\). pTN-ensemble Monte-Carlo simulation results: red dots (obtained in a compression process), green dots (obtained in an expansion process); Exact analytical result given by Eq. (29): lines (the same results as those shown in Fig. 3).
