The compression ratio of an Otto cycle as shown in the figure below is VA/VB = 6.00. At the beginning A of the compression process, 525 cm3 of gas is at 110 kPa and 20.0°C. At the beginning of the adiabatic expansion, the temperature is TC = 730°C. Model the working fluid as an ideal gas with γ = 1.40.
