Okay; apologies.  I see that I did misinterpret your meaning as I had  
originally speculated.  Nevertheless, this is still wrong.  The  
amount of work done--and, thus, the final energy, temperature,  
pressure, and entropy as well--depends on the details of how the  
piston is moved.  This is not an isentropic process.
