The temperature of 0.054 moles of monatomic ideal gas increases as it expands at constant pressure of 3.00 atm from 440. mL to 660. mL. Next, the pressure and temperature are allowed to drop at constant volume until the temperature has returned to its original value. Last, the gas is compressed at constant temperature back to 440 mL. (a) Draw the P-V diagram. (b) Indicate on each side whether heat is flowing in or out. (c) How much work is done by the gas during the whole process? (d) How much heat flows into the gas?

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...
