In regards to "Maxwell's Demon" In regards to the Maxwell's Demon thought experiment and violation of the Second Law of Thermodynamics, I have a scenario that results in (a) question(s). First I won't pretend to have extensive knowledge of Thermodynamics so bear with me... Say we have two insulated chambers of temperatures T1 and T2, and we create a small opening connecting them. Criticism of Maxwell's Demon violating the 2nd Law of Thermodynamics lies in energy expenditure by the so called "Demon" monitoring the motion of all molecules in the chambers. Let's say, in a new scenario, there is no demon controlling this opening. Let it be open indefinitely. Is there not a non-zero probability that all molecules possessing kinetic energy above T1 can make their way to the first chamber and all molecules possessing kinetic energy less than T2 make their way to the second chamber? If the system remains in this configuration indefinitely, will it not violate the Second Law?
