Thermodynamic data for fifty reference elements

Technical Report ·
OSTI ID:6310348
; ;
This report is a compilation of thermodynamic functions of 50 elements in their standard reference state. The functions are C[sub p][sup 0], (H[sup 0](T) - H[sup 0](0)), S[sup 0](T), and -(G[sup 0](T) - H[sup 0](O)) for the elements Ag, Al, Ar, B, Ba, Be, Br2, C, Ca, Cd, Cl2, Co, Cr, Cs, Cu, F2, Fe, Ge, H2, He, Hg, I2, K, Kr, Li, Mg, Mn, Mo, N2, Na, Nb, Ne, Ni, O2, P, Pb, Rb, S, Si, Sn, Sr, Ta, Th, Ti, U, V, W, Xe, Zn, and Zr. Deuterium D2 and electron gas e[sup [minus]] are also included. The data are tabulated as functions of temperature as well as given in the form of least-squares coefficients for two functional forms for C[sub p][sup 0] with integration constants for enthalpy and entropy. One functional form for C[sub p][sup 0] is a fourth-order polynomial and the other has two additional terms, one with T(exp -1) and the other with T(exp -2). The gases Ar, D2, e[sup [minus]], H2, He, Kr, N2, Ne, O2, and Xe are tabulated for temperatures from 100 to 20,000 K. The remaining gases Cl2 and F2 are tabulated from 100 to 6000 K and 1000 to 6000 K. The second functional form for C[sub p][sup 0] has an additional interval from 6000 to 20,000 K for the gases tabulated to 20,000 K. The fits are constrained so that the match at the common temperature endpoints. The temperature ranges for the condensed species vary with range of the data, phase changes, and shapes of the C[sub p][sup 0] curves.
