1. Using Pj = e^-BE/Z in the Gibb's form for the entropy, show that F = kb Tln (Z), where F = U - TS is the Helmholtz free energy. Here Z= e^-BE is the canonical partition function ...

Modern oil tankers weigh over a half-million tons and have lengths of up to a quarter of a mile. Such massive ships require a distance of 5.0 km (about 3.0 mi) and a time of 22 min to come to a stop from a top speed of 26 km/h.
