A piston-cylinder device contains 1.101 kg of nitrogen gas at 120 kPa and 27 degrees C. The gas is now compressed slowly in a poly tropic process which PV^(1.38) = constant. The process ends when the volume is reduced by one-half. Determine the entropy change of nitrogen during this process.

Change in entropy _________ kJ/K (round to four decimal places)
