Relativistic Transformation of Thermodynamic Parameters and Refined Saha Equation

The relativistic transformation rule for temperature is a subject under debate more than 110 years. Several incompatible proposals exist in the literature, but final resolution still missing. In this work, we reconsider problem of rules number thermodynamic parameters, including temperature, chemical potential, pressure, entropy and enthalpy densities perfect fluid using kinetic theory. analysis carried out fully covariant manner, explicit above quantities are obtained both Minkowski Rindler spacetimes. Our results suggest that moving appears to be colder, supporting proposal by de Broglie, Einstein Planck contrast other proposals. Moreover, case fluid, our work indicates that, total particles box whose bottom parallel horizon proportional area bottom, independent height box, provided sufficiently close horizon. dependence particle implies tend gathered toward hence implicitly determines distribution potential system, whereas additive may find some applications explaining law black hole entropy. As product, also obtain relativistically refined version famous Saha equation which holds
