All i need is the drawing of this. A piston–cylinder device initially contains 0.07 m3 of nitrogen gas at 130kPaa and 1800C. 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 ( 0C) and the boundary work (kJ) done during this process.
