Argon is contained in a spring-loaded piston-cylinder device. The process equation for this device is P = av + b where a and b are constants determined by the spring. The argon starts at 100 kPa, 27 oC, and 0.01 m3. The device is now heated to 1470 kPa, 0.0364 m3. How much argon is contained in this device? What is the total amount of work produced by this system?
