1. As shown in the figure, oxygen fills the cylinder of a piston-cylinder assembly. The initial volume and pressure are 2 m 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. 0 m = 2 kg V = 2 m P = 1 bar V = 2V Patm = 1 bar 1. As shown in the figure, oxygen fills the cylinder of a piston-cylinder assembly.
