pressure Volume 2. A heat engine using an ideal diatomic gas (only translational and rotational internal energy, no vibrational internal energy) consists of three processes that make a complete cycle: process A to B is isobaric expansion at a pressure of PA = P3 = 255.0kPa , process B to Cis a constant volume cooling process with Vo =VC, process to A is an adiabatic compression. The volume at point A is V= 0.00140m”, the temperature at point Ais T, = 425.0K , The temperature at point Cis T = 293.0K a. What is the volume at point C, V, ? Note: Vo =V, are unknowns in this problem b. What is the pressure at point C, Pc c. What is the network done during one cycle, Wmnet? d. In which process or processes is heat transferred into the gas? What absolute value of heat is transferred into the gas during each cycle, Q.1? e. In which process or processes is heat transferred out of the gas? What absolute value of heat is transferred out of the gas during each cycle, |2c|? f. What is the thermal efficiency of this engine, & ? g. What is the change in entropy in the C to A process, ASCA? h. What is the change in entropy in the A to B process, ASB ?
