  The thermodynamic approach to non-equilibrium dynamics describes the state of
macroscopic systems by means of a collection of intensities or intensive
variables. The latter are by definition the differentials of the entropy with
respect to the set of extensive constraints. The environment is directly
involved in controlling the intensities. The isolation paradigm is negated. The
general principles substanciating the approach are restated and expanded to
multi-component systems. The procedure is applied to the prediction of
transport processes (viscosity and thermal conductivity) of mixtures of atomic
gases. Theoretical results are compared with published experimental data.
