Air is compressed in a piston–cylinder assembly from p1 = 15 lbf/in2, T1 = 500°R, V1 = 9 ft3 to a final volume of V2 = 1 ft3 in a process described by Assume ideal gas behavior and neglect kinetic and potential energy effects. Using constant specific heats evaluated at T1, determine the work and the heat transfer, in Btu.
