Nitrogen in the amount of 2 kg fills a 0.05 m3 piston-cylinder device at 500 kPa. The piston is now moved by changing the weights until the volume is half of its original size. During this process, the temperature of the gas is maintained constant. Determine the final pressure in the device. Given the gas constant of nitrogen is R = 0.2968 kJ/kg-K
