1.1.1 Microscopic description of thermodynamic equilibrium

Noting the packaging, P, and the food, F, thermodynamic equilibrium corresponds to a situation where the cumulative free energy of P and F, noted G P+F , is minimal, and characterizes the state towards which the packaging-food system spontaneously evolves when P and F are placed in contact. It corresponds to thermal, mechanical and chemical equilibrium between the two compartments. At uniform pressure...
