Query: Maxwell's Conjecture of the Demon creating a Temperature Difference is
  False   We argue that Maxwell's demon is incapable of creating a nonzero temperature
difference. Hence, it does not destroy equilibrium and the second law is never
at risk, contrary to the claim by Maxwell and accepted by many. It is therefore
remarkable that despite this, the demon paradox has been a valuable source of
new ideas. We use two independent arguments, one using classical equilibrium
thermodynamics by extending Brillouin's approach, and the other one using
equilibrium statistical mechanics and the central limit theorem.
