1. The compression ratio of an air-standard Otto cycle is 9.5. Prior to the isentropic compression process, the air is 100 kPa, 35°C, and 600cm³. The temperature at the end of the isentropic expansion process is 800K. Using the specific heat values at room temperature 25°C, determine (35%)

 (Assume constant specific heats for air at room temperature 25°C. Cp=1.005kJ/kgK, Cv=0.718kJ/kgK, R=0.287 kJ/kgK and k=1.4
