I just need the drawing of both figure, no need solution. 1. 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. 2. 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 (0C) of air and the heat transferred during compression (kJ/kg).
