Local thermodynamics of inhomogeneous fluids at equilibrium

Extensive thermodynamic parameters of inhomogeneous fluids in thermal equilibrium are expressed as integrals of corresponding locally defined quantities.

Zusammenfassung:Extensive thermodynamic parameters of inhomogeneous fluids in thermal equilibrium are expressed as integrals of corresponding locally defined quantities. In particular, the distinction between the grand canonical potential and the integrated mechanical pressure is discussed in terms of scale invariance, and a similar analysis is made of the Helmholtz free energy.
