* Your answer is incorrect.
A gas undergoes a process in a piston-cylinder assembly during which the pressure-specific volume relation is pv¹.2 = constant.
The mass of the gas is 0.4 lb and the following data are known: p₁ = 160 lbf/in.², V₁ = 1 ft³, and p2 = 300 lbf/in.² During the process,
heat transfer from the gas is 2.1 Btu. Kinetic and potential energy effects are negligible. Determine the change in specific internal
energy of the gas, in Btu/lb.
