Introduction
I would like to show in this discussion that Maxwell’s Demon does not violate the second law of thermodynamic but violates the first law (Angus, Armstrong, and Reuck).This can be shown by demonstrating that Maxwell’s Demon Process (MDP) can be turned to a step process which is a reversible cycle.
According to the Maxwell’s Demon Process, An ideal gas is contained in a very tough or rigid walled container is divided into two halves using a rigid partition with a hole or a trap door on it. The vessel and the trap door should be thermally insulated such that they don’t contribute to any temperature change in the process. When the MD is made to operate the trap door in such a way that it only allows faster molecules to move from left to right and only slower molecules to move from right to left, then there will be a temperature different in the vessel. This will leave both the surrounding and the MD with no temperature change.
When the partition is removed, the Why perpetual free energy machines do not work? Vessel goes back to its normal temperature showing that the process is reversible. It is only when the process is reversible that we can say that the first law of thermodynamic is violated.
Why perpetual motion energy machines do not work.
An orderly motion can be converted to a disorderly motion by dissipative processes like friction (Angus, Armstrong, and Reuck). For perpetual motion is not prohibited by the fundamental of physics but physical objects and its properties does. Perpetual motion simply meaning moving forever, the perpetual machines require a constant supply of energy as they will only take as much energy as they are being provided from the initial ‘kick’ to the delivery of energy, once energy or work is extracted from the machine the motion either decreases or it stops.
Perpetual machines also are hard or impossible to test, if a device for a long time and it is in a continuous motion and has no signs of slowing down it would take forever to test it, and we can say that the machine is not a perpetual motion device. If there are no dissipative forces like friction a perpetual motion energy machine would have its efficiency to about 100%, and it would be easy for them to work but this forces exist therefore making it hard for the machines to work.
Perpetual motion machines verse first and second law of thermodynamics
Thermodynamic laws have been violated by the perpetual motion machines. Firstly, in 1880s John Gamgee developed an ammonia-filled “zeromotor” and this is a vivid failure of how perpetual motion machines violate the second law of thermodynamic namely, that in converting heat into work some heat is lost.
The perpetual motion machines have constantly be viewed as isolated systems by scientists and they violate the first law of thermodynamic (Hultgren and Ralph Raymond 106). It is impossible to have a machine that produce 100% efficiency as the dissipation forces like frictions cannot be avoided. Some perpetual motion machines produce work without energy input, it goes with no say that the first law of thermodynamics is violated.
Conclusion
Basing the argument from the ongoing discussion, it is evidence to conclude that Maxwell did violate the first law of thermodynamic and conserved the second law of thermodynamic. As per the perspective of perpetual motion energy machines, both the first and the second laws of thermodynamic are violated in one or another which have been clearly stated in the above discussion. The question of whether perpetual motion machines exist is on, for it is evidence their existence is almost zero percent.
