Problem
1. A balloon behaves so that the pressure is P=C2V1/3 and C2 = 100 kPa/m. The balloon is blown up with air from a starting volume of 1 m3 to a volume of 4 m3. Find the final mass of air, assuming it is at 25?C, and the work done by the air.
2. Consider a piston/cylinder setup with 0.5 kg of R-134a as saturated vapor at -10oC. It is now compressed to a pressure of 500 kPa in a polytropic process with n = 1.5. Find the final volume and temperature and determine the work done during 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.
