A system comprises one mole of an ideal gas at 0 degree C and 1 atm. The system is subjected to the following processes, each of which is conducted reversibly: a. A 10-fold increase in volume at constant temperature b. Then a 100-fold adiabatic increase in pressure c. Then a return to the initial state along a straight-line path in the P-V diagram Calculate the work done by the system in step (c) and the total heat added to or withdrawn from the system as a result of the cyclic process.
