In this and the next question, you will analyze a heat engine whose cycle is given below. 2 3 V2 V1 The segments 12 and 23 are constant temperature and pressure respectively, while segment 31 is adiabatic. The cycle runs clockwise as shown. You may assume that the working substance is one mole of ideal gas, with f quadratic degrees of freedom per atom. For each segment, determine in the table whether: heat is leaving or entering the system; work done on the system is positive or negative; the temperature increases or decreases. Segment Heat Work on the system Temperature 1 to 2 OUT V +|VE V constant V 2 to 3 IN V |VE V increases V 3t01 NONE V |VE V decreases V Continuing with the same cycle as question 1 (reproduced below), assume that we have a system with f = 6 and V1/V2 = 3.5. Let TMAX be the highest temperature and TMIN be the lowest temperature along the cycle. P (a) Compute the ratio TMAX /TMIN. (b) Calculate the efficiency of this heat engine. Answers are within 5% tolerance
