He asserts that gravity will create a thermal lapse rate that is there in his
isolated ideal gas in a near - Earth gravitational field in thermal
equilibrium — the condition that an air column will
reach after all irreversible relaxation processes such as conduction, convection, and radiation have completed.
If we leave his
isolated ideal gas alone for a long time, energy will redistribute until the gas
reaches «energy
equilibrium».
He went well out of his way to
isolate the gas and leave it alone so it would
reach «energy
equilibrium», whatever that is supposed to mean, but there you have it.
Another possibility is that the exchange would continue only until the new, combined wire - gas system
reached its own
equilibrium, in which we would not in general expect the gas to exhibit the same mean - molecular - kinetic energy profile it did when it was
isolated.
Where he directly stated that an
isolated atmosphere in a gravitational field
reaches isothermal
equilibrium, as first demonstrated by Gibbs some 120 years ago?
You based this on the following definition of the 2nd law: «'' When two
isolated systems in separate but nearby regions of space, each in thermodynamic
equilibrium in itslef, but not in
equilibrium with each other t first, are at some time allowed to interact, breaking the isolation that separates the two systems, and they exchange matter or energy, they will eventually
reach a mutual thermodynamic
equilibrium.»
«When two
isolated systems in separate but nearby regions of space, each in thermodynamic
equilibrium in itself, but not in
equilibrium with each other at first, are at some time allowed to interact, breaking the isolation that separates the two systems, and they exchange matter or energy, they will eventually
reach a mutual thermodynamic
equilibrium.»
