Enthalpy and the first law of black hole
Proceedings of Science, CNCFG2010.
In black hole thermodynamics a cosmological constant contributes a pressure to the equation of
state whose the conjugate variable is a ‘volume’. It is shown that, for a negative cosmological
constant, this ‘thermodynamic volume’ is the volume of space excluded by the event horizon,
when quantum gravity corrections are ignored. This applies to black holes in any dimension with
any event horizon geometry compatible with Einstein’s equations, such as spheres, tori, spaces of
constant negative curvature or, in general, any Einstein space with constant Ricci scalar. Quantum
corrections to the volume are calculate for the BTZ black hole.
