Many potential applications of graphene in nanotechnology depend on its thermo-mechanical stability. We have calculated the temperature dependent properties such as the  volume thermal expansion, and thermal expansion coefficient of the graphene using the equation of state (EOS) based on thermodynamic variables. A simple theoretical method is applied to determine the thermal expansion and thermal expansion properties of graphene. The model employed in the present study consists of only two input parameters and independent of potential. The results achieved as reported in this paper are found in good agreement with those obtained from QHA-GGA ab- initio study [25].
