In this article, the dynamic components and temperature values of modified Chaplygin gas, which has the equation of state P=Aρ-B/ρ^α were obtained as a function of entropy and volume for the universe filled with modified Chaplygin gas, first at α=0 and then at α=1. All symbols used in the derivation are defined explicitly, and the entropy-dependent integration functions are fixed through the thermodynamic relation T=(∂U/∂S)V. The original contribution of this work is the combined derivation of the Weinhold curvature and the corresponding Christoffel coefficients for modified Chaplygin gas within the same thermodynamic phase-space framework. The signs of the thermodynamic curvature (R=0, R>0, R
