The Compressibility of Gaseous Xenon. I. An Equation of State for Xenon and the Weight of a Liter of Xenon

Abstract

The compressibility of xenon containing 0.14 mole percent of krypton has been measured from 16.65° (the critical temperature) to 300°C and over the density range 1 to 10 mole per liter. The constants of the Beattie‐Bridgeman equation of state for the sample used and for pure xenon have been determined from these measurements. The constants for pure xenon are R=0.08206, A₀=4.6715, a=0.03311, B₀=0.07503, b=0, c=30.02×10⁴ in units of normal atmos, liter per mole, and °K (T°K=t°C+273.13). The weight of one liter of Xe at a pressure of one standard atmosphere is calculated from its molecular weight (131.3) and the above parameters to be 5.897 g per liter at 0°C and 5.467 g per liter at 70°F.
