Abstract:Temperature, a fundamental metric in thermal energy characterization, encounters intriguing exceptions during phase transitions, where it maintains a constant value despite significant internal energy alterations. Equipartition theorem also failed in interpreting these phenomena. In this study, we introduce a novel framework termed "potential energy temperature (Tpot)" and associated degrees of freedom (Dpot) to provide deeper insights into phase transitions. Our investigations reveal that Tpot diverges consid… Show more
