Entropy Change in Reversible Thermodynamic Processes
This content covers the definition of a reversible thermodynamic process, whose defining property is that entropy does not change (dS = 0). Using the second law of thermodynamics, this implies zero heat transfer (Q = 0), and combined with the first law (dU = ΔW), this constrains the relationships among internal energy, work, and temperature for such a process. The concept sits within classical thermodynamics, distinguishing reversible from irreversible processes (where entropy strictly increases) and from isothermal processes (where internal energy is constant).
