Recent works have provided new insight into the black hole laws of thermodynamics by considering volume and pressure into the formalism. As a consequence, in this framework, the thermodynamic interpretation of the black hole's mass changes and black holes exhibit chemical-type phase behaviors, such as liquid/gas phase transitions similar to a Van der Waals fluid, triple points similar to that of water, and re-entrant phase transitions that appear in gels. Moreover, this new perspective seems also to have implications in black holes analog models. In this talk, I will describe some of these developments and potential applications.
