    Groups of Order 144: Abelian Groups Up to Isomorphism

    Yeah, I realized that that counted towards the 10. It's the midst of finals so the brain's on the fritz. I was just going to take this post down, thanks though!

    Groups of Order 144: Abelian Groups Up to Isomorphism

    I'm going insane. The question is: List all abelian groups (up to isomorphism) of order 144. There are 10 non-isomorphic groups of order 144 and I only have 9. Here they are: Z2 X Z2 X Z2 X Z2 X Z3 X Z3 Z2 X Z2 X Z2 X Z2 X Z9 Z4 X Z2 X Z2 X Z3 X Z3 Z4 X Z2 X Z2 X Z9 Z8 X Z2 X Z3 X Z3 Z8 X Z2...

    How Do You Derive U, T, P, C_v, and V for This Thermodynamic System?

    Given S=A*(N*V*U)^{1/3} where A is a constant. a) What is U, T, and P for the system? b) what are C_v and V? c) 2 identical bodies consisting of a material obeying the equations found in A. N and V are the same for both and they are initially at temps T_1 and T_2. The two bodies are brought...
