Air (ideal gas) inside a cylinder filled with a frictionless piston undergoes a polytrophic process having an exponent n = 1.33. The initial pressure of the air is 3.34 MPa and the T (final) is 750 K and during the process the volume of the air is increased by 55%. Determine the amount of heat transfer to the surrounding during the process in (kJ/kg). Use average specific heats at room Temperature.
