r'''Method to compute the entropy integral of heat capacity from 
         `T1` to `T2`.

        Parameters
        ----------
        T1 : float
            Initial temperature, [K]
        T2 : float
            Final temperature, [K]

        Returns
        -------
        dS : float
            Entropy difference between `T1` and `T2`, [J/mol/K]
