Is there any way for the entropy to increase in an closed adiabatic sy

[Dili]

1) Is there any way for the entropy to increase in an closed adiabatic syatem?

2) what are the mechanisms of entropy generation within a closed thermodynamic system?

Thank you

Just off the top of my head...

1. I think so - the usual example of a partition separating two different pockets of gas comes to mind.

2. Statistics, it is simply more likely for a system to be in a disordered state in an ordered one. That's not to say that a system is guaranteed to increase in entropy, it is just overwhelmingly likely in cases (such as mixing gases) where the number of particles in the system is very large.
