Ukrainian Journal of Physics| Zusammenfassung: | The cell fluid model with a modified Morse potential is studied. The supercritical states are considered with respect to the possibility of the construction of a separation boundary between liquid-like and gas-like behaviors. We will calculate three different lines that can be used for this purpose: the loci of the isothermal compressibility maxima, the loci of the thermal expansion coefficient maxima, and the line, where the effective chemical potential is zero, M = 0. By the symmetry of the functionals for the partition functions, the condition M = 0 in fluids is analogous to the absence of an external field in the Ising model. |
