One mole of an ideal monatomic gas is used as the working substance of engine that operates on the cycle shown in Fig. 24-20. Calculate (a) the work done by the engine per cycle. (b) the heat added per cycle during the expansion stroke abc, and (c) the engine efficiency. (d) What is the cannot efficiency of an engine operating between the highest and lowest temperature present in the cycle? How does this compare to the efficiency calculated in (c)? Assume that p₁ = 2p₀, V₁ = 2v₀, p₀ = 1.01 × 10⁵ Pa, and V₀ = 0.0225 m³,
