The model for an ultra-relativistic gas is here considered in the framework of Extended Thermodynamics. The closure, satisfying exactly the principles of relativity and of entropy, is obtained by following the approach «at a macroscopic level». Our results are compared with the ones of the kinetic approach.
Il modello di un gas-relativistico viene qui preso in considerazione, nell’ambito della Termodinamica Estesa. Seguendo l’approccio a «livello macroscopico», viene trovata la chiusura soddisfacente esattamente il principio d’entropia e quello di relatività. I nostri risultati vengono confrontati con quelli dell’approccio cinetico.
