Question
Assess the accuracy of these statements concerning
entropy and thermodynamic equilibrium: (I) Entropy measures the disorder or randomness within a system. (II) At thermodynamic equilibrium, a system's entropy reaches its maximum. (III) Entropy decreases in reversible processes.Solution
Entropy is indeed a measure of disorder or randomness within a system, and at thermodynamic equilibrium, entropy is maximized, reflecting the most disordered state. Statement (III) is incorrect because entropy remains constant in a truly reversible process and increases in real, irreversible processes.
