일반물리학 1 — Temperature, Heat, and the First Law of Thermodynamics: Problem 40

40 As a gas is held within a closed chamber, it passes through the cycle shown in Fig. 18-37. Determine the energy transferred by the system as heat during constant-pressure process CA if the energy added as heat \(Q_{AB}\) during constant-volume process AB is 25.0 J, no energy is transferred as heat during adiabatic process BC, and the net work done during the cycle is 15.0 J.
