(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two objects A and B, with an equal number, N, of molecules are brought into thermal contact. The first has entropy [tex] S_A = Nkln(U_A/N)[/tex] and the second has entropy [tex] S_B = 3/2 * Nkln(U_B/N)[/tex]. What is the final temperature?

2. Relevant equations

[tex]\frac{1}{T} = \frac{\partial S}{\partial U}[/tex]

3. The attempt at a solution

My process would be to take

[tex]\frac{\partial}{\partial U}Nkln((U_A + \Delta U) / N) = \frac{\partial}{\partial U}3/2 * Nkln((U_b - \Delta U)/N)[/tex]

And solve for delta U. Is this the best way to approach the problem?
