  The thermodynamic parameters like energy density, pressure, entropy density,
temperature and particle density are determined from the transverse momentum
distributions of charged particles in Pb-Pb collisions at the LHC. The results
show a clear increase with the centrality and the beam energy in all
parameters. It is determined that in the final freeze-out stage the energy
density reaches a value of about 0.039 GeV/fm$^3$ for the most central
collisions at $\sqrt{s_{NN}}$ = 5.02 TeV. This is less than that at chemical
freeze-out where the energy density is about 0.36 GeV/fm$^3$. This decrease
approximately follows a $T^4$ law. The results for the pressure and entropy
density are also presented for each centrality class at $\sqrt{s_{NN}}$ =
  2.76 and 5.02 TeV.
