I agree that pV is a valid thermodynamic potential, but my point was that thermodynamic potentials are not functions of one another, but rather are obtained from one another by Legendre transform. | |

However, the fomula defining the Helmholtz free energy has much broader validity than for perfect gases. Also making differences between thermodynamic variables and potentials is not clarifying. Think for example $pV$: as a function of $(V,T,\mu)$ it is a thermodynamic potential. | |
