• Regarding an isotropic Lorentz gas, thermal transport properties are discussed atthe most elementary level. Lorentz's original equations for heat and matter flows arereformulated in terms of kinetic quantities of dilute gases to clarify the nature oftransport coefficients from the viewpoint of linear nonequilibrium thermodynamicsincluding the Onsager reciprocal theorem. Especially referring to thermal diffusionproperties of the Lorentz gas, Lorentz's transport equations are studied by using thetransported internal energy 7"' and the internal energy of transport E' which areconnected with E " =E ' A-E, where E is the partial molecular internal energy. In thiscase, 71"= kT /2 and E = (3 /2)kT, and hence E" '= 2 kT, using the Boltzmann conslant k and the temperature T. A special case, E' being a constant activation energyof usual diffusion, is briefly discussed.
