The equation of state developed on the basis of the analysis of the isobar heat capacity behaviour in critical area
Annotation
On the basis of the phenomenological theory of critical phenomenas and a Benedek hypothesis the scale equation of state in variables density and temperature for an asymptotic neighbourhood of a critical point is output. The offered equation of state meets all requirements of a scale hypothesis and coincides on the structure with the scale equations of state constructed within the limits of a method of pseudo-critical points. As gauge at build-up of a nonparametric scale equation of state for the first time it is offered to use scaling component of an isobar heat capacity. The offered equation of state meets all requirements of a scale hypothesis and coincides on the structure with the scale equations of state constructed within the limits of a method of pseudo-critical points.Use as independent variables of density and temperature allows to use the offered approach for build-up of the wide-band equations of state satisfying to a scale hypothesis.
