Thermal equilibrium of A and B, microstates and quanta

  1. Feb 25, 2008 #1
    1. The problem statement, all variables and given/known data

    System A consisting of 10^23 oscillators for which hw=10^-20 J, is in thermal contact with system B, consisting of 2x10^23 similar oscillators. The joint system has internal energy 3x10^3 J. Calculate the number of quanta in A and B, and the temperature, when A and B are in thermal equilibrium.

    2. Relevant equations



    3. The attempt at a solution

    So i have this: W(N,Q) = (N+Q-1)!/[(N-1)!Q!] N is number of oscillators and Q is number of quanta.

    For a generic system and W(total) for the system A and B = [tex]\Sigma[/tex]W1(E1)W2(U-E1)

    Where W is the number of microstates.

    How do i find the number of quanta in A and B?
