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

Entropy The number of microstates (W) in a system is related to the entropy (S) of the system. A system with fewer microstates has lower entropy. A system with more microstates has higher entropy. All spontaneous endothermic processes exhibit an increase in entropy. Entropy, like enthalpy, is a state function and is therefore
