Steam in a piston-cylinder assembly undergoes a polytropic process, with n = 2, from an initial state where V₁ = 3.50880 ft³, p₁ - 350 lb/in², and u₁= 1322.4 Btu/lb to a final state where u₂ = 1036.0 Btu/lb and v₂ = 3.393 ft³/lb. The mass of the steam is 2.0 lb. Changes in kinetic and potential energy can be neglected. Determine the change in volume, in ft3, the energy transfer by work, in Btu, and the energy transfer by heat, in Btu. Step 1 Determine the change in volume, in ft³. ΔV= 3.28 Hint Your answer is correct. Step 2 W = i ft3 Determine the energy transfer by work, in Btu. Btu Attempts: 2 of 4 used
