The generalization of charged AdS black hole specific volume and number density

Abstract

In this paper, by proposing a generalized $specificvolume$, we restudy the $P-V$ criticality of charged AdS black holes in the extended phase space. The results show that most of the previous conclusions can be generalized without change, but the ratio ${\tilde{\rho }}_c$ should be $3\tilde{\alpha }/16$ in general case. Further research on the thermodynamical phase transition of black hole leads us to a natural interpretation of our assumption, and more black hole properties can be generalized. Finally, we study the number density for charged AdS black hole in higher dimensions, the results show the necessity of our assumption.
