In this work we study the thermodynamic properties of the pion gas startingfrom the realistic elastic scattering phase-shifts obtained from ChiralPerturbation Theory and using the virial expansion. In particular we study thestate equation and the behavior of the quark condensate as a function of thetemperature and the density.Comment: 16 Pages, 12 figure
