Abstract
We study various thermodynamical variables of importance like quark number susceptibilities, energy density, pressure, specific heat, speed ofsound in the framework of PNJL model as the hadronic system undergoes a phasetransition from the confined to deconfined phase. I will also briefly discussthe extension of PNJL model by incorporating a SU(3) measure to improve thebehaviour of the traced polyakov loop. We make a quantitative comparisonwith the Lattice QCD results. Based On the above study resulting phase diagram will also be discussed.
