**XENON**

Xenon provides high accuracy thermodynamic properties for elemental xenon using the fundamental equation of state developed by O. Sifner and J. Klomfar, "*Thermodynamic Properties of Xenon from the Triple Point to 800 K with Pressures up to 350 MPa*," J.Phys. Chem. Ref. Data, Vol. 23, No.1, pp. 63-152, (1994). This correlation is also presented in a more convenient form in the textbook by R.T. Jacobsen, S.G. Penoncello, and E.W. Lemmon, "Thermodynamic Properties of Cryogenic Fluids", Plenum Press, 1997, ISBN 0-306-45522-6. The thermodynamic property correlations are valid for temperatures between triple point (161.36 K) and 800 K at pressures up to 350 MPa.

__Range of applicability for transport function correlations:__
