Only the second part dissipates into internal energy and generates entropy. This generation is shown to be d II = (U / T) dT. Thermodynamic arguments are extended to transport phenomena. It is shown that a part of local rate of entropy generation is related to local rate of thermal deformation by s (iii) = –U / T(dT / dxi), where U(i) = q / T,q(i) being the rate of heat flux.
