and so on. In all, if the thermodynamic space is D dimensions, then there will be D equations for each potential, resulting in a total of D 2 equations of state because 2 thermodynamic potentials exist. If the D equations of state for a particular potential are known, then the fundamental equation for that potential (i.e., the exact differential of the thermodynamic potential) can be determined. This means that all thermodynamic information about the system will be known because the fundamental equations for any other potential can be found via the Legendre transforms and the corresponding equations of state for each potential as partial derivatives of the potential can also be found.
