Find the total work and the heat transfer from the ambient

Question

Problem

1. Air in a piston/cylinder arrangement is at 110 kPa, 25^oC, with a volume of 50 L. It goes through a reversible polytropic process to a final state of 700 kPa, 500 K and exchanges heat with the ambient at 25^oC through a reversible device. Find the total work (including that of the external device) and the heat transfer from the ambient.

2. A rigid container with a volume of 200 L is divided into two equal volumes by a partition. Both sides contain nitrogen; one side is at 2 MPa, 300^oC and the other is at 1 MPa, 50^oC. The partition ruptures, and the nitrogen comes to a uniform state at 100^oC. Assuming the surroundings are at 25^oC, find the actual heat transfer and the irreversibility 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.
