## 9.13 Equation Confusion

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### 9.13 Equation Confusion

Hi all. I was wondering why in question 9.13, the solution manual says to use the equation delta S = nRln (T2/T1). Isn't the equation for entropy change involving temperature nC(T2/T1)?

This is rare instance where the solutions manual is incorrect. Please refer to the link on his website Solution Manual Errors for this problem.

Does anyone know what the soluition manual's equation can be applied to or does it not exist in reality?
