PREDICTION OF THE TEMPERATURE-DEPENDENCE OF THE LIMITING DIFFUSION-COEFFICIENTS OF 5 HELIUM-FLUOROMETHANE SYSTEMS FROM DIFFUSION-COEFFICIENTS AT 300 K AND LIMITING THERMAL-DIFFUSION FACTORS AT THE SAME TEMPERATURE AND ZERO PRESSURE

Thermal diffusion factors alpha(T) are reported at 300 K for five bina ry systems consisting of helium and a fluoromethane. The data are extr apolated to zero pressure and used to predict the temperature dependen ce of the binary diffusion coefficients of these systems. (C) 1996 Ame rican Institute of Physics.
