Ten moles of ideal gas, in the initial state P1=10atm, T1=300K, are taken round the following cycle:
a. reversible change of state along a straight line path on the P-V diagrm to the state P=1 atm, T=300K,
b. A reversible isobaric compression to V=24.6 liters, and
c. A reversible constant volume process to P=10atm.
How much work is done on or by the system during the cycle? Is this work done on the system or by system?
