A thought experiment challenging this law requires an imaginary creature to sort particles based on energy, is and often called Maxwell's Demon.
The simplest formulation of this law is known as the Clausius statement. It was originally formulated in Reflections on the Motive Power of Fire by the founder of a namesake heat cycle, Sidi Carnot. Another formulation of this law states that it is impossible to convert heat completely into work and is known as the Kelvin statement. A thought experiment challenging this law requires an imaginary creature to sort particles based on energy, is and often called Maxwell's Demon. For 10 points, identify this law which states that the entropy of the universe is always increasing.
