Problem
1. Saturated water vapor at 60oC has its pressure decreased to increase the volume by 10% while keeping the temperature constant. To what pressure should it be expanded?
2. Ammonia at 20oC with a quality of 50% and a total mass of 2 kg is in a rigid tank with an outlet valve at the top. How much vapor mass can be removed through the valve until the liquid is gone, assuming that the temperature stays constant?
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.
