Its apparent violation of T-symmetry was resolved with the H-theorem developed by Boltzmann. It can be mathematically stated as the indefinite integral of the reciprocal of temperature with respect to heat is always positive, while a thought experiment in which it is violated is called Maxwell's Demon. Equivalent to the statement that not all heat of a system can be converted to useful work, it was first posited by Rudolph Clausius. For 10 points, identify this law which states that the entropy of the universe always increases.
