(25 points) A heat engine performs the cycle abco as shown in the figure with 2 300 K 500 K 9.0 moles of an ideal gas. Path ca is an b adiabatic process. The temperatures at points a and b are 300 K and 500 K, respectively. The volume at point c is 0.20 me. The adiabatic constant (y) is 02 AN 1.40. Use this cycle for the following questions. a) (5 points) How much heat enters the gas during each cycle? The universal AN gas constant is R = 8.314 J/mol- YRIGHT, 2024 ALLA DVI 0.20 m3 N YRIGHT, 2022 ALEX BURAN b) (12 points) How much heat is wasted by the gas during each cycle? During which process is heat discarded? The universal gas constant is R = 8.314 J/mol.K BURAN YRIGHT, 2022 ALEX BURAN YRIGHT, 2022 ALEX BURAN YRIGHT, 2022 ALEX BURAN c) (8 points) What is the efficiency of this engine?
