Problem 1. Boundary Work (20 points) A frictionless piston-cylinder contains 0.2 kg of methane gas at 120kPa and 290 K. Nitrogen is then compressed until the final pressure reaches 250kPa. Heat is removed during the process so that the temperature in the device remains constant. Calculate the boundary work. Where Fluid: Oxygen Isothermal process State 1 State 2 Equation 4.7 To get the specific volumes, use the ideal gas equation or use NIST Solving for v Therefore, the boundary work is
