The viscosity coefficient of Ne at 298 K and at a pressure of 1 atm is n(Ne) = 32 Pa s ( 1Pa s = 10^-6 kg /m.s). Calculate: a) the coefficient of thermal conductivity and b) the coefficient of self-diffusion. of Ne in the aforementioned experimental conditions, in the International System of Units (S.I.). Rely on the following relationships: where l is the mean free path, N * the number of molecules per m3 gas and the average and speed.
