일반물리학 1 — Entropy and the Second Law of Thermodynamics: Problem 12

12 A 2.5 mol sample of an ideal monatomic gas undergoes the reversible process shown in Fig. 20-21. The scale of the vertical axis is set by \(T_s = 400.0 \text{ K}\) and the scale of the horizontal axis is set by \(S_s = 20.0 \text{ J/K}\). (a) How much energy is absorbed as heat by the gas? (b) What is the change in the internal energy of the gas? (c) How much work is done by the gas?
