Question

Constants A cylinder with a piston contains 0.300 mol of oxygen at 2.50x10° Pa and 345 K. The oxygen may be treated as an ideal gas. The gas first expands isobarically to twice its original volume. It is then compressed isothermally back to its original volume, and finally it is cooled isochorically to its original pressure. Part D Find the work done during the final cooling, IVO AQ R O 2 ?
