1) (10 points) An ideal gas undergoes a complete cycle composed of subprocesses A, B, and C as shown in the following PV diagram: P B A The temperature change during process A is the same as during process B. Rank the magnitude (absolute value) of the heat transfer for each subprocess (QA|,QB], and (Qc)) from greatest to smallest. There are no phase changes.

2) (10 points) 3 mol of an ideal gas undergoes a process a + b + c shown in the following PV diagram: P (105 Pa) bl a 3 2 с V (10-3 m) 1 2 3 4 5 6 The type of gas is unknown but UCD physicists measure its heat capacity to be 99.8 J/K when pressure is constant. Determine the total heat transfer for the process a + b + c. There are no phase changes.
