## entropy and pressure

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

### entropy and pressure

How is entropy related to pressure? And does this change depending on what type of system is being dealt with?

### Re: entropy and pressure

One equation for entropy is delta S = nR*ln(P1/P2). From this, it follows that increasing pressure decreases entropy and decreasing pressure increases entropy.

### Re: entropy and pressure

We know that delta s = nRln(V2/V1). Since pressure and volume have an inverse relationship, delta S = nRln(P1/P2).
