Abstract

‘Relativistic thermodynamics’ should be understood not as a generalization of a non-relativistic theory but as an application of a general thermodynamic framework, neutral as to spacetime setting and allowing arbitrary conserved quantities, to the specific case of relativity. That framework gives an unambiguous result as to the thermodynamics of relativistically moving systems (an answer coinciding with Einstein’s, and Planck’s, original results.) Thermodynamic temperature is unambiguously defined as rate of change of energy with entropy at constant momentum; that said, its operational significance is limited and other measures of energy/entropy covariance, which incorporate momentum transfer, are often more useful.

Additional Information: This is a very substantial (pretty much from scratch) revision of my preprint 'On Relativistic Temperature'. The content is largely unchanged but the structure is substantially different. hopefully in ways which make the core ideas clearer.
