Plot the heat capacity as a function of temperature for aluminium, using the Einstein model.

2. Relevant equations

The Einstein model for heat capacity:

3. The attempt at a solution

The model assumes that the frequencies of all the harmonic oscillators in the material are the same. But does it mean "same for all temperatures" or "same for a given temperature"? And if the latter is true, will I need to find a function [tex]\epsilon (T)[/tex]? Because otherwise the right hand side of the Cv equation wil have two free variables. Thankful for help, my textbook is very unclear about this.
