چکیده	In this paper, we use equation of state, temperature and bulk viscosity of the quark gluon plasma and calculate some cosmological and thermodynamical quantities. In order to obtain such quantities we choose special case of energy density in terms of Hubble parameter. We apply the approximation solution and obtain the exact form of scale factor, temperature and bulk viscous stress. Finally, we draw some figures for the geometric and thermodynamic quantities in terms of time
