6. A piston-cylinder device initially contains 0.07 m³ of nitrogen gas at 130kPaa and 180°C. The nitrogen is now expanded to a pressure of 80kPaa polytropically with a polytropic exponent whose value is equal to the specific heat ratio. Determine the final temperature (C) and the boundary work (k) done during this process. Page | 93

7. At a certain process, the specific heat at polytropic process of air is 0.3075kJ/kg-
k. Under the same process, air initially at STP is being compressed until the pressure
becomes 200kPaa. Determine the final temperature (°C) of air and the heat
transferred during compression (kJ/kg).
