1) (23 points) A sample of a monatomic gas is taken through the engine cycle illustrated on the p-V graph. In terms of only Po, Vo, and/or C constants, find the following quantities: The work done during the entire cycle. b) The heat absorbed or released (i) during the entire cycle, and (ii) during each process of the cycle (ab, be, and ca). (Hint: Are any of these "special case" processes?) c) The efficiency of the cycle. O 2V. 3V. Answers: a) PoVo; b) (i) PoVo, (ii) +1.5poVo, +10p,Vo, -10.5poVo; c) 0.0870, or 8.70% (Note: OH is the sum of only the positive ( terms, so ( is not included.)2) {12 points] A. Carnot refrigerator is in a room which is at 25.0 \"C. The refrigerator does 16.0 kl of work to extract an unknown amount of heat from the freezer compartment, and in the process it releases TSJI} kl of heat to the room. Determine {a} the heat extracted from the freezer compartment, (h) the coefcient of performance of this refrigerator, and (c) temperature of the freezer compartment in \"(3.
