Example Problem - Boundary Work of a Polytropic Process

A frictionless piston-cylinder device contains 2 kg of nitrogen at 100 kPa and 300 K. Nitrogen is now compressed slowly according to the relation PV1.4=Constant until it reaches a final temperature of 360 K. Calculate the work input during the process, and be sure to indicate direction (kJ).

How would you find the final pressure in this case?

Use PV=MRT
