ABSTRACT:
This report is a compilation of thermodynamic functions of 50 elements in their reference state. The functions are Cop, {H°(T)-H°(0)}, S°(T), and - {G°(T)-H°(0)} 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- 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 Cop with integration constants for enthalpy and entropy. One functional form for Cop is a fourth-order polynomial and the other has two additional terms, one with T-1 and the other with T-2. The gases Ar, D2, e-, 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. The polynomial functional form for Cop for all these gases is split into two temperature intervals-200 to 1000 K and 1000 to 6000 K. The second functional form for Cop 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 properties 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 Cop curves.
