Work in Reversible Process vs Work in Irreversible Process

Postby Kimberly Wagas 1H » Tue Jan 12, 2016 3:38 pm

The textbook states that "Provided the initial and final states are the same, a change carried out reversibly always does more work than a change carried out irreversibly"?

Why is the amount of work a system can do greater in reversible processes as opposed to in irreversible processes?

In a reversible process, you don't lose energy as heat, while in an irreversible process, some energy is lost as heat.

Are open, closed, or isolated systems reversible?

If you graph the two, it is pretty easy to see that a reversible process does more work. The area under the curve is greater.
