Abstract

We derive a class of equations of state for a multi-phase thermodynamic system associated with a finite set of order parameters that satisfy an integrable system of hydrodynamic type. As particular examples, we discuss one-phase systems
such as the van der Waals gas and the effective molecular field model. The case of $N-$phase systems is also discussed in detail in connection with entropies depending on the order parameter according to Tsallis' composition rule.
