Abstract
The present paper derives an expression for the change in internal energy and enthalpy of the black holes using first law of thermodynamics and showing that the change in internal energy and enthalpy are the manifestations of same thing at constant pressure and volume. The paper also shows that the spinning black holes with spin a*→1 do not radiate energy and mass of the black hole becomes infinity for zero surface gravity.
