A frictionless piston–cylinder device, shown in initially contains 0.01 m3 of argon gas at 400 K and 350 kPa. Heat is now transferred to the argon from a furnace at 1200 K, and the argon expands isothermally until its volume is doubled. No heat transfer takes place between the argon and the surrounding atmospheric air, which is at 300 K and 100 kPa. Determine the maximum work that can be produced during this process.
Nitrogen at an initialstate of 300 K, 150 kPa, and 0.2 m3 is compressed slowly in anisothermal process to a final pressure of 800 kPa. Determine the work doneduring this process. Also, explain the negative sign in the answer.
