Apiston confines 0.200 mol ne(g) in 1.20 at 25 degree c. two experiments are performed. (a) the gas is allowed to expand through an additional 1.20 l against a constant of 1.00atm. (b) the gas is allowed to expand reversibly and isothermally to the same final volume. calculate the work done by the gas system in these two processes, respectively. which process does more work? (revised from 6/e exercise 8.11) show calculation details.
