Our question states :
"A system enclosed by an impermeable, adiabatic boundary is necessarily in thermodynamic equilbrium. True or false"
The textbooks only define thermodynamic equilibrium for two systems. I.e systems have to be in thermal equilbrium (same T), and there must be no unbalanced forces acting between them (mechanical eq.) and no chemical reactions occurring (chemical eq.). Also there must be no exchange in matter between systems.
Firstly, are no unbalanced forces or chemical reactions allowed to act between the systems, or within each system as well?
Also, I am not sure how these properties relate to one system on its own. If the system is isolated from surroundings by adiabatic impermeable walls, then it doesn't even have to be in thermal equilibrium with its surroundings (or anything else), and I thought that this was one of the fundamental things about thermodynamic eq. I can see that there may well be unbalanced forces and chemical reaction occurring within the system, so the answer is probably going to be false, but I'm not sure because my understanding of thermodynamic eq. is hazy. I'd also appreciate it if somebody could give me a good book reference or internet link.
Thanks
