Problem
1. A piston/cylinder device contains 0.3 lbm of mixture of 40% methane and 60% propane by mass at 540 R, 15 psia. The gas is now slowly compressed in an isothermal (T = constant) process to a final pressure of 40 psia. Show the process in a P-V diagram, and find both the work and the heat transfer in the process.
2. Two insulated tanks, A and B, are connected by a valve. Tank A has a volume of 30 ft3 and initially contains argon at 50 lbf/in.2, 50 F. Tank B has a volume of 60 ft3 and initially contains ethane at 30 lbf/in.2, 120 F. The valve is opened and remains open until the resulting gas mixture comes to a uniform state. Find the final pressure and temperature.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
