Wilhoit Equation: Ideal-gas Heat Capacity Cpo and derived properties

Details of access to equation parameters:

annotated evaluation results showing constant parameters (left to right): T_ref, I, J, S(298.15K) naught and fitted parameters (top to bottom): a_0, a_1 / 10^5, a_2, a_3, a_4, a_5 / 10^6, a_6, a_7

Tref is the reference temperature for representation of enthalpy and entropy

I is the integration constant for calculation of enthalpy increments

J is the integration constant for calculation of entropies

So(298.15 K) is the entropy of the ideal gas at T = 298.15 K and p = 100 kPa
