Physical Sens of Potentials

This lecture covers the physical sense of potentials, including the definition of a reservoir, equilibrium between subsystems, heat and enthalpy, systems at fixed pressure, work and free energy. The slides discuss the concept of a tank as a system coupled with another, the balance between subsystems, and the characteristics of a system at constant pressure. The lecture also delves into the balance of a system coupled to a working tank, the minimization of enthalpy, and the equilibrium state between subsystems. Furthermore, it explores the concept of a heat tank subject to external work, the equilibrium with the reservoir, and the mechanical work performed on a system at a constant temperature.
