Carbon dioxide (CO2) is compressed in a piston–cylinder assembly from p1 = 0.7 bar, T1 = 280 K to p2 = 14 bar. The initial volume is 0.2 m3. The process is described by pV1.25 = constant. Assuming ideal gas behavior and neglecting kinetic and potential energy effects, determine the work and heat transfer for the process, each in kJ, using constant specific heats evaluated at 300 K, and data from Table A-23.

A 0.2 m3 piston-cylinder initially contains 400 K air. A heavy frictionless piston maintains a pressure of 500 kPa abs. Then, a weakness in the cylinder wall blows out and creates a hole. Air escapes through the hole until the piston drops far enough to cover the hole. At that point, the volume is half the initial volume. During this process, 75 kJ of heat is transferred to the 100 kPa, 300 K surroundings. Using Cp = 1.005 kJ/kg-K and...
