Chapter 42, Problem 42.54CP

(a)

To determine

To show: The bulk modulus for a system of $N$ free electrons in a volume $V$ at low temperatures is $B=\frac{5}{3}p$ and why the external pressure is equal to the internal pressure of the system.

(b)

To determine

The bulk modulus for the electrons in copper.

(c)

To determine

The fraction of the actual bulk modulus of copper due to free electrons and the factor responsible for the remaining fraction of the bulk modulus.
