Answer: Figure 20-27 shows a reversible cycle through

Chapter , Problem 29

(choose chapter or problem)

Figure 20-27 shows a reversible cycle through which 1.00 mol of a monatomic ideal gas is taken. Assume that P = 2po, V = 2Vo, Po = 1.01 X 105 Pa, and Vo = 0.0225 m3 Calculate (a) the work done during the cycle, (b) the energy added as heat during stroke abc, and (c) the efficiency of the cy- Volume cle. (d) What is the efficiency of a Fig. 20-27 29. Carnot engine operating between the highest and lowest temperatures that occur in the cycle? (e) Is this greater than or less than the efficiency calculated in (c)?
