7. An air standard Otto cycle at the start of the isentropic compression has P₁ = 100 kPa and T₁ = 27°C. The compression ratio is 10 and during the heat addition process 1000 kJ/kg are supplied. Using the cold air standard analysis method, the net work for this cycle is most nearly equal to: A. 960 kJ/kg B. 900 kJ/kg C. 602 kJ/kg D. 333 kJ/kg E. Cannot be determined with the given information.
