## 4F.9

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

### 4F.9

Why is it that we plug in the inverse of pressures as the volumes when solving the entropy of an ideal gas ?

### Re: 4F.9

because in the ideal gas equation: PV=nrT P and V are inverses (as one increases the other decreases)
