= = = Air is compressed in a piston-cylinder assembly from p1 = 25 lbf/in2, T1 = 500R, V1 = 9 ft3 to a final volume of V2 = 1 ft) in a process described by pvl.15 = constant. 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
