Find the heat capacity of the system

  1. Jun 25, 2009 #1
    1. The problem statement, all variables and given/known data

    A system posesses three energy levels E1=ε, E2=2ε, E3=3ε with degeneracies g(E1)=g(E3)=1 , g(E2)=2
    Find the heat capacity of the system.

    2. Relevant equations



    3. The attempt at a solution

    i got the partition function and then differenciated it twice which gives me an expression for C however its not correct and i can't see how to bring it the degeneracites i presume they are needed
