Tom,
I admit I started skimming it after the first few pages, but it all seem to prove my point that the effects of time are not thermodynamically reversible. The relevant part;
"Reversibility
A reversible process is a process where the effects of following a thermodynamic
path can be undone be exactly reversing the path.
An easier definition is a process that is always at equilibrium even when undergoing a
change.
Phase changes and chemical equilibria are examples of reversible processes.
Ideally the composition throughout the system must be homogeneous.
- This requirement implies that the no gradients, currents or eddys can exist.
- To eliminate all inhomogeneities, a reversible process must occur infinitely
slow!
- Thus no truly reversible processes exist. However, many systems are
approximately reversible. And assuming reversible processes will greatly aid
our calculations of various thermodynamic state functions.
Reversibility during pressure changes ensures that
p = pex
That is, the pressure on the inside of the container is always equal to the pressure
exerted on the outside of the container."
So basically even only the most contained, ordered and simple processes can be reversed. What am I missing?
