일반물리학 1 — Entropy and the Second Law of Thermodynamics: Problem 3

3 Figure 20-19 shows a reversible cycle through which 1.00 mol of a monatomic ideal gas is taken. Assume that \(p = 2p_0\), \(V = 2V_0\), \(p_0 = 1.01 \times 10^5 \text{ Pa}\), and \(V_0 = 0.0335 \text{ m}^3\). Calculate (a) the work done during the cycle, (b) the energy added as heat during stroke \(abc\), and (c) the efficiency of the cycle. (d) What is the efficiency of a 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)?
