a time in the very distant future must come when all of the molecules of Gas A would be in Box A and all of the molecules of Gas B would be in Box B. This would be a very fleeting state and would quickly rediffuse all over again.
We know that to sort a mixture of gasses into separate compartments the sum of whose volumes is equal to the original volume, a certain minimum work must be done, pursuant to the Second Law of Thermodynamics. If this is so, does it imply that to do any sorting operation, there exists an irreduceable minimum energy that must be expended? In other words, no computer could be constructed that would sort a list alphabetically which would not consume an irreduceable minimum of energy.
