32   Interim Conclusions

According to the previous considerations, the following quantities are invariant in the sense of STR :

The following quantities are transformed by multiplication by the root factor:

The following values are transformed by dividing by the root factor:

There is no simple transformation in the sense of section 2 for the following process variable:

The following laws continue to apply mutatis mutandis for all inertial observers:

For non-relativistic ideal gases we further have the invariant relationships

Up to now we did not use the final result of the first part of this treatise:

T'  =  T

Combining the invariance of temperature with the results of sections 22 to 30 will yield a quite simple final statement: All important equations of thermodynamics are invariant in the sense of STR !
