Hm, I'm pretty much stuck on a thermodynamics problem.
If you consider two identical masses of water at temperatures T1 and T2, what is the global increase in entropy after they have reached thermal equilibrium.
The best I could come up with is [del]S = m*C*ln(T2/T1).
The answer listed in the book is 2m*C*ln[(T1+T2)/2Sqrt(T1*T2)]
I am completely and utterly stuck. Any help would be greatly appreciated.
