You recall an algorithm from elementary school for factoring a number N: Divide out all factors of 2, then of 3, then of 4, then of 5, then of 6, then of 7, etc. Finally, divide out all factors of N (of which there can be at most one).

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.
