The thermodynamics of SGTE from 0 to 298.15K are extrapolated by two methods. One is the extrapolation of polynomial model. The other is the extrapolation of Debye model. To take example for copper, the extrapolation methods are introduced in detail. By means of the constrained nonlinear least squares curve fitting arithmetic, two sets of parameter values have been determined. The expressions of the thermodynamic functions C_p (T) and G (T)-H (298.15K) at 0-298.15 K are presented. The polynomial model can accurately fit the experimental data, give the electronic heat capacity and the T=0 Debye temperature Θ0, be easy to use with a computer and, more importantly, has mathematically explicit expressions to link with the SGTE expressions, but has an excessive number of terms. The Debye model has a smaller number of terms and can give the electronic heat capacity and the average Debye temperature, but it is more complicated mathematically, its evaluation requires the help of computer and the low temperature data stored in the form of Gibbs energies, as do SGTE, has not explicit expressions.
