... these two limits leave a big working range - any quick
motion of the piston by a human arm is bound to be just fine. Carl
Notice that a) not until the piston speed is nearly half the rms
speed of the gas molecules does this formula give final temperatures
that are even as large as those predicted for an infinitely slow,
isentropic compression and that b) for piston speeds much greater
than the rms speed, the formula gives enormous final temperatures
that would never begin to be realized due to rapid conduction of heat
to the walls. I conclude that the formula has very limited
applicability and, thus, as Carl does, that the Adiabatic Gas Law
apparatus suffers no noticeable ill-effects due to the non-
quasistatic nature of the compression.
