Air is in a piston-cylinder device initially at 800 psia and 2500°F. The air is now expanded such that Pv1.2 = constant. The final volume is 8 times the original volume. Determine the final temperature and pressure. Also, determine the work done and the heat transferred per unit mass during this process.
