QUESTION II: 0.5 m³ of air at T1 = 67 °C, P1 = 700 kPa undergoes a polytropic expansion to a final pressure of 350 kPa. The process follows pV13 constant and the work done by the air is 175 kJ. Assuming ideal gas behavior for the air, and neglecting kinetic and potential energy effects, determine: (a) the final temperature, in °C. (b) the heat transfer, in kJ. Air

QUESTION II: 0.5 m' of air at Ti = 67 °C, Pi = 700 kPa undergoes a polytropic expansion to a final pressure of 350 kPa. The process follows pV3= constant and the work done by the air is 175 kJ. Assuming ideal gas behavior for the air, and neglecting kinetic and potential energy effects, determine: (a) the final temperature, in °C. (b) the heat transfer, in kJ. Air
