In the present work, we study the effect of including the curvature term, in addition to the volume term, in the density of states used in the calculation of the projected color-singlet partition function of the Quark-Gluon Plasma (QGP), on some features characterizing the phase transition to this new phase of matter. By investigating the behavior of some physical quantities well describing the mixed system with temperature for varying volume, we especially examine the behavior with volume of the shift of the effective transition temperature in a finite volume from the true one, to determine the corresponding scaling exponent. We compare the present results to those obtained in our previous works, where we have used a color-singlet QGP partition function derived with a density of states containing the volume term only.
