2. When a system can go fromstate 1 to state 2 by several different processes, the work done onthe system will be the same for all processes.
3. A quasi-static process isone in which the system is never far from being inequilibrium.
4. When a system can go fromstate 1 to state 2 by several different processes, the amount ofheat absorbed by the system will be the same for allprocesses.
