Hello,
I have a small problem concerning the free expansion of a gas.
https://www.physicsforums.com/attachment.php?attachmentid=20388&stc=1&d=1252066499
The two chambers are separated by a movable piston (without friction). Obviously the gas will expand because it puts pressure p on the piston. It will move the piston against the right chamberwall.
I think the gas has done work: W=p*delta(V), but apparently it hasn't: Chemical principles by Steven S. Zumdahl page 418.
What's my mistake??
