A system consisting of 0.32 mole of a monatomic ideal gas occupiesa volume of 2.20L at point A at a pressure of 2.40 atm. The systemis carried through a cycle consisting the following threeprocesses:
1. The gas is heated at constant pressure until its volume is 4.40Lat point B.
2. The gas is cooled at constant volume until the pressuredecreases to 1.20 atm at point C.
3. The gas undergoes an isothermal compression back to pointA.
(a) Sketch the pV-diagram for the cycle.
(b) What is the temperature at points A, B, and C?
(c) Find W,Q, and ?U for each process and for the entire cycle.
