## Homework Statement

Show that the adiabatic bulk modulus of a free electron gas can be given by

[tex] B= \frac{2nE_{F}}{3}[/tex]

where

n-number density

[tex] E_{F}[/tex] -Fermi energy

## Homework Equations

I started with the adiabatic bulk for an ideal gas

[tex] K=\gamma P[/tex]

where [tex] \gamma=\frac{C_{p}}{C_{v}}[/tex]

but i do not have idea how to continue with the problem to obtain solution.

I appreciate any help.
