A closed system consisting of 10 lb of air undergoes a polytropic process from p₁ = 65 lbf/in², v₁ = 4 ft3/lb to a final state where p2 = 20 Ibf/in², v₂ = 12 ft3/lb. Determine the polytropic exponent, n, and the amount of energy transfer by work, in Btu, for the process. Step 1 Determine the polytropic exponent, n, for the process.
