Problem
1. A 100-L rigid tank contains nitrogen (N2) at 900 K and 3 MPa. The tank is now cooled to 100 K. What are the work and heat transfer for the process?
2. A constant-pressure piston/cylinder assembly contains 0.2 kg of water as saturated vapor at 400 kPa. It is now cooled so that the water occupies half of the original volume. Find the work and heat transfer done in the process.
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.
