A piston-cylinder assembly contains carbon monoxide modeled as an ideal gas with constant specific heat ratio k = 1.4. The carbon monoxide undergoes a polytnoptic expansion with n = k from an initial state, where T = 200 Farenheit Degrees and p1 = 40 lbf/in^2, to a final state, where the volume is twice the initial volume. Determine (a) the final temperature, in Farenheit, and final pressure, in lbf/in^2, and (b) the work and heat transfer, each in btu/lb.
