Abstract
The present paper gives a model for the change in the internal energy and enthalpy (Mahto et al., 2016) and reviews it to propose a model for change in Gibb’s free energy of the Reissnner-Nordstrom black hole. This also calculates their values in AGN concluding that the enthalpy and internal energy has the same values and they are just double to that of Gibb’s free energy for the same mass.
