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

### 4F.11) 7th edition

In the solutions manual for problem 4F.11) of the 7th edition of the textbook, they use the formula for change of entropy that delta S = nRln(T2/T1). Is this a formula that we can normally use? I thought it only applied to changes in volume.

Yes you can use this for a change in T
