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

  1. Sep 25, 2007 #1
    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.
