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

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.

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