A piston-cylinder device contains 0.78 kg of nitrogen gas at 140 kPa and 37°C. The gas is now compressed slowly in a polytropic process during which PV1.3 = constant. The process ends when the volume is reduced by one-half. Determine the entropy change of nitrogen during this process. The gas constant of nitrogen is R= 0.2968 kJ/kg-K. The constant volume specific heat of nitrogen at room temperature is Cr=0.743 kJ/kg-K. (Round the final answer to five decimal places.) The entropy...
