Chapter 6: Entropy and the Boltzmann Law

Chapter 6: Entropy and the Boltzmann Law. S = k ? n W. This eqn links macroscopic property entropy and microscopic term multiplicity. k = Boltzmann constant (Appendix A) States tend toward maximum W and therefore maximum S. Eqn 6.1 S = k log W. S = -k ? p i ?n p i.
