A cylinder with a piston contains 0.300 mol of oxygen at 2.50×105 Pa and 360 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.

a. Find the heat added to the gas during the initial expansion

b. Find internal-energy change of the gas during the initial expansion.

c. Find the heat added during the final cooling;
