Two crystalline solids at absolute zero (0 Kelvin) can create perpetual motion machine?
Perpetual motion machine: Motion that continues indefinitely without any external source of energy; impossible in practice because of friction.
The lowest recorded temperature, -273.15 degrees Celsius, is known as absolute zero. It is said (not proven) that atoms cease to oscillate at this temperature. It is the temperature at which all motion stops at the atomic level. Meaning, no atomic motion = no energy released = no heat = no entropy = no disorder. SAY you have an environment in which you can create a crystalline solid shaped in a U at absolute zero. You then place a smaller piece, also at absolute zero, on the inside edge of the U and let go. There is no heat given off between either piece, so there is no friction. No external factors.
Perpetual motion machine? Although its not much of a machine.
