If one mole of air/fuel mixture (rigid diatomic gas) is initially at 20 °C, is compressed and expanded 7-fold as part of the Otto cycle, and 4 kJ of heat is generated by burning the air/fuel mixture, calculate: (i) the temperature after each stage of the Otto cycle; (ii) the heat absorbed/expelled during each stage of the cycle; and (iii) the efficiency of the Otto cycle.
