| contents | We investigated the form and implications of the local first law of black hole thermodynamics in relation to an observer located at a finite distance from the black hole horizon. Our study is based on the quasilocal form of the first law for black hole thermodynamics, given by $δE=\frac{\barκ}{8π}δA$, where $δE$ and $δA$ represent the changes in the black hole mass and area, respectively, and $\barκ$ denotes the quasilocal surface gravity. We show that even at a finite distance, the quasilocal law still holds. It shows how the first law scales with the observer's location. |
