The working substance of an engine is 1.00 mol of a monatomic ideal gas. The cycle begins at P1=1.00 atm and V1=24.6L. The gas is heated at constant volume to P2=2.00atm. It then expands at constant pressure until its volume is 49.2L. The gas is then cooled at constant volume until its pressure is again 1.00 atm. It is then compressed at constant pressure to its original state. All the steps are quasi-static and reversible. Calculate the TOTAL work done...

A three-step cycle is undergone by 3.8 mol of an ideal diatomic gas: (1) the temperature of the gas is increased from 230 K to 710 K at constant volume; (2) the gas is then isothermally expanded to its original pressure; (3) the gas is then contracted at constant pressure back to its original volume. Throughout the cycle, the molecules rotate but do not oscillate. What is the efficiency of the cycle?
