A piston-cylinder device initially contains 0.054 m^3 of nitrogen gas at 150 kPa and 115 C. The nitrogen is now expanded to a pressure of 110 kPa polytropically with a polytropic 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.
