1. Argon in the amount of 1.5 kg fills a 0.04-m3 pistoncylinder device at 550 kPa. The piston is now moved by changing the weights until the volume is twice its original size. During this process, argon’s temperature is maintained constant. Determine the final pressure in the device.
2. A rigid tank contains 20 lbm of air at 20 psia and 70°F. More air is added to the tank until the pressure and temperature rise to 35 psia and 90°F, respectively. Determine the amount of air added to the tank.
