Using Energy Concepts and the Ideal Gas Model

Two kg of oxygen fills the cylinder of a piston–cylinder assembly. The initial volume and pressure are 2 m³ and 1 bar, respectively. Heat transfer to the oxygen occurs at constant pressure until the volume is doubled. Determine the heat transfer for the process, in kJ, assuming the specific heat ratio is constant, k = 1.35. Kinetic and potential energy effects can be ignored.
