Finding the energy of a system using the partition function

  1. Aug 7, 2010 #1
    1. The problem statement, all variables and given/known data

    In part a) to this question I calculated the partition function which is Z = 1 + 3/e + 5/e^2

    2. Relevant equations

    I can't find an equation relating U to Z.

    3. The attempt at a solution

    If someone has an explanation or a link to an equation that would be great. Thanks.

    What's your situation, what type of particles are you considering?

    it does not specify but we deal mostly with ideal gases.

    Wikipedia has a brief summary.
