An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27C, and 800 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into account constant specific heats at room temperature. The properties of air at room temperature are c_p = 1.005 kJ/kgK, c_v = 0.718 kJ/kgK, R = 0.287 kJ/kgK, and k = 1.4.

Determine the pressure and temperature at the end of the heat-addition process. (You must provide an answer before moving on to the next part.)

The pressure at the end of the heat-addition process is kPa.

The temperature at the end of the heat-addition process is K.
