Dec 19, 2018 at 20:35 comment added user197851 Thermodynamic equations of state are not restricted to relations between $P,V,T$ and $N$. Most of the thermodynamic relations that you will see are based on converting from one set of variables to another. Having specified $\mu$ and $T$, all other intensive thermodynamic variables are defined. For example, $\rho$ and $P$ may each be expressed as a function of those two. Usually, the function is not known (except for a few exactly soluble models), but that doesn't matter.

Dec 19, 2018 at 20:17 comment added Sha Vuklia I don't really see why $P=P(\mu,T)$, but I can see that if we have fixed $V$ and $T$, and fixed $N$ I suppose, since we're in diffusive equlibrium, than the equation of state which relates $P,V,T$ (and $N$?) will fix $P$.
