Web4 de mai. de 2024 · The heat capacity is the slope of internal energy U with temperature (at constant volume) C V = ( ∂ U ∂ T) V and the internal energy is related to the partition function as U T = R T ( ∂ z ∂ T) V and so also to the entropy. The classical thermodynamic relationship is S = S 0 + ∫ 0 T C p T d T where C p is a function of temperature. Share
