Abstract
Thermal conductivities λ of neon, argon, and xenon were measured at 760 mm Hg in the ranges 1000–1500 °K (neon, xenon) and 1000–2500 °K (argon). The data were correlated by expressions of the form λ = a Tb, where a and b are constants depending upon the gas. The results were compared with (1) existing data, (2) viscosity measurements η, by means of the coefficient f = λ/(2.5ηCv), and (3) values calculated from an extended law of corresponding states. The correlations obtained from the measurements were found to describe well the thermal conductivities of all three gases not only within the temperature ranges of the experiments but also over the range 900–2500 °K.
