   "Final state" implies time.   
      
   Atoms A and B in gas state are inserted into a container in proportion   
   1:1. The final state is an almost perfect distribution of a mixture of   
   both gases. We do not expect the gases to appear separated after some   
   time. That is the accepted final state of a smooth distribution for two   
   gases in a container at room temperature say.   
      
   But is it the final state?   
      
   Surely not, since if not given any external energy, the final state of   
   the mixture could be a separated mixture of frozen A and B at almost   
   absolute zero. Let's suppose that when freezing, gases A and B do not   
   mix easily.   
      
   Time is always there in all physics. The concept of "final state"   
   implies time, you see?
