Air is contained in a piston-cylinder assembly, initially at 40 lbf/in^2. And 600R the air expands in a poly tropic process with n=k=1.4 until the volume is doubled. Modeling the air as an ideal gas with constant specific heats, determine:
The final temperature, in R, and pressure, in lbf/in^2
The work and heat transfer, each in Btu per lb of air
