I read this discussion but I am interested in how the entropy is obtained as a function of pressure. Namely, how can you determine a following integral for an ideal gas:(adsbygoogle = window.adsbygoogle || []).push({});

$$S(p) = -\int_{0}^{p} \frac{nR}{p}dp $$

when you need to start from 0 pressure?
