The JAVA applet below simulates four reversible thermodynamic processes. The thermodynamic system in each process is 0.333 mole of an ideal monatomic gas (C_v = 12.47 J/mole-deg). The ideal gas is contained in a cylinder with a movable piston. Click one of the four "Process" buttons to begin an animation and the "Stop" button to end the animation. Allow the animation to run for at least 20 seconds. The "Heat Reservoir" is a "hot" bath from which the ideal gas absorbs heat. The "Heat Sink" is a "cold" bath that absorbs heat from the ideal gas. The initial step in each process is "Step 1" and the final step is "Step 2". At the end of the simulation click the "PV Plot" button to see a pressure-volume plot of the process. The initial and final pressures, volumes, and temperatures of the ideal monatomic gas and the area under the PV curve are displayed on the plot.

    Use the applet in the design and performance of experiments to answer the following questions. See the Tutorial for Experiment: Thermochemistry for an example and help.

1. What type of thermodynamic process is "Process 1"?
2. Calculate q, w, DE and DH for "Process 1". See the equations on the last page of the lecture notes.
3. How much of the absorbed heat in "Process 1" is used to do PV work?
4. How is the remaining heat used in "Process 1"?
5. Calculate q, w, DE and DH for "Process 2".
6. How is the absorbed heat used in "Process 2"?
7. Calculate q, w, DE and DH for "Process 3".
8. Is work done by the system on the surroundings or by the surroundings on the system in "Process 3"?
9. Why does the internal energy of the gas increase in "Process 3"?
10. Calculate q, w, DE and DH for "Process 4".
11. What type of thermodynamic process is "Process 4"?
12. Why does the pressure of the gas decrease in "Process 4"?
