Ummmm ..entropy is the logarithm of multiplicity we all know that, perhaps the words are not really saying that directly but I'm sure they tried their best ;)
Entropy is a function of state indicating direction of equilibrium. It says nothing about the path of change. It is common for a system to have a potential state of higher entropy but have no available path to make the transition. Hydrogen and oxygen gas mixture will sit inertly unless/until sparked. Thermo-'dynamics' is a misnomer; entropy and energy are system state functions, the 'correct' nomenclature would be thermostatics.
The verbiage under Boltzmann's equation is just plain wrong.

ReplyDeleteThe reference to time is out of context.
ReplyDeleteI think they assumed constant k = time constant
ReplyDeleteOr they referred at the number of ways to change the system (w) as actions that will occur during a period of time. What do u think?

ReplyDeleteFYI Boltzmann's constant has no time unit.
ReplyDeleteBill, I think the idea is to share info between us and learn one from another. I find it really useful ;)
