This scientist corrected the isotherm of a van der Waals gas by replacing an oscillating section below the critical temperature with a horizontal line splitting the curve into two equal areas. The equality of mixed partial derivatives can be used to derive a set of relations named for this man equating various partials of thermodynamic quantities. This physicist developed a distribution function describing the velocities of molecules in ideal gases that is also named for Boltzmann, and he added a displacement current term to correct Ampere's law. He also conceived of a being that could violate the second law of thermodynamics. For 10 points, name this British scientist who put together the four fundamental equations of electromagnetism and has a namesake demon.
