A cylinder with a piston contains 0.300 molmol of oxygen at 2.50×105 PaPa and 350 KK . 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.
