A cylinder contains oxygen gas at a pressure of 2.00 atm. The volume is 4.00 L, and the temperature is 300 K. Assume that the oxygen may be treated as an ideal gas. The oxygen is carried through the following processes:
(1) Heated at constant pressure from the initial state (state 1) to state 2, which has 450 K
(2) Cooled at constant volume to 250 K (state 3).
(3) Compressed at constant temperature to a volume of 4.00 L (state 4).
(4) Heated at constant volume to 300 K, which takes the system back to state 1.
A) Calculate Q and W for each of the four processes.
B) Calculate the net work done by the oxygen.
C) What is the effiency of this device as a heat engine? How does this effiiency compare with that of a Carnot-cycle engine operating between the same minimum temperatures of 250K and 450K?
