Comment to the reply to "On the thermodynamics of inhomogeneous perfect fluid mixtures"

TL;DR

This paper refutes a recent claim that a thermodynamic scheme for perfect fluid mixtures is only compatible with FRW universes, demonstrating broader applicability to Szekeres and Stephani universes.

Contribution

It corrects a previous assertion, showing that the thermodynamic scheme applies to more universe models than previously claimed.

Findings

The thermodynamic scheme is compatible with Szekeres and Stephani universes.

The previous claim of incompatibility was incorrect.

The scheme's applicability extends beyond FRW universes.

Abstract

In spite of a recent reply by Quevedo and Z\'arate (gr-qc/0403096), their assertion that their thermodynamic scheme for a perfect fluid binary mixture is incompatible with Szekeres and Stephani families of universes, except those of FRW ones, remains wrong.
