Note that , and are measurable, at least in principle, so that the ’s may be calculated from (105). Therefore it follows that the constitutive theory has led to specific results. All constitutive coefficients are now explicit: The ’s can be calculated from the thermal equation of state and the ’s may be measured.
It might seem from (106) and (97) that the dynamic pressure is of order but this is not so as was recently discovered by Kremer & Müller . Indeed, the second step in the Maxwell iteration for provides a term that is of order , see also . That term is proportional to the second gradient of the temperature so that it may be said to be due to heating or cooling.
Specific results of the type (104, 105) can also be calculated for degenerate gases with the thermal equation of state for such gases. That equation was also derived by Jüttner . The results for 14 fields may be found in Müller & Ruggeri [39, 40].
