摘 要：Thermodynamics of phase transition for a black hole in 5D Einstein-Gauss-Bonnet gravity with a negative cosmological constant is *** the Bekenstein-Hawking entropy is adopted,we find the heat capacity,volume expansion coefficient and isothermal compressibility are divergent at the critical points,which implies the existence of phase *** fact that the phase transitions are indeed second order is revealed by studying the Ehrenfest s equations and the Prigogine-Defay *** near the critical points,we also explicitly calculate the critical exponents of the relevant thermodynamic quantities at fixed charge or fixed *** is shown that the corresponding critical exponents satisfy the thermodynamic scaling *** Generalized Homogeneous Function hypothesis is also checked by studying the Helmholtz free energy,which is shown to be consistent with the thermodynamic scaling law.
