Thermal Diffusion Factors from the Measurements on a Trennschaukel: Ar–He and Kr–Ne

Abstract

Measurements of the thermal diffusion factors α_T are made on an eight‐tube glass trennschaukel with its two ends at about 0° and 100°C. The two systems investigated are Ar–He and Kr–Ne at a composition for which some special interest exists. The α_T results are compared with the other available literature values, and the previously observed anomalies are explained on the basis of these new measurements. For the Ar–He mixture containing 81.6% Ar we get an α_T value of 0.30 at 318.6°K. Similarly for a Kr–Ne mixture (27.5% Ne) the value is found to be 0.30₃ at 318.5°K.
