When combined with Fourier's Law, this principle yields the heat partial differential equation. Its analogue for black holes contains a surface gravity over 8 pi term and gives the change in mass. Hess' law is a consequence of this law, which was developed by James (*) Joule, and it results from the application of the law of conservation of energy to thermodynamics. For 10 points, name this law that can stated as "d U equals Q minus W," showing that change in internal energy is equal to heat transferred minus work done.
