Chapter 20: Entropy and the Second Law of Thermodynamics The Conservation of Energy law allows energy to flow bi-directionally between its various forms. For example in a pendulum, energy continually goes to/from kinetic energy and potential energy. Entropy is different: No conservation law the Entropy change S associated with an irreversible process in a closed system is always greater than or equal to zero. Ice in water 1. only from ice into water 2. only from water into ice 3. both ways Consider putting some ice into a glass of water. Conservation of energy would allow energy to flow: Entropy and the Second Law of Thermodynamics That direction is set by a quantity called Entropy Only one of these scenarios happens, so something must be controlling the direction of energy flow.
