Question: A pistoncylinder device initially contains 0.07 m3 of nitrogen gas at 130 kPa and 120C. The nitrogen is now expanded to a pressure of 100

A piston–cylinder device initially contains 0.07 m3 of nitrogen gas at 130 kPa and 120°C. The nitrogen is now expanded to a pressure of 100 kPa polytropically with a poly tropic exponent whose value is equal to the specific heat ratio (called isentropic expansion). Determine the final temperature and the boundary work done during this process.
