A cylinder with a piston contains 0.300 moles of oxygen at 2.20×10^5 pa and 340 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 work done by the gas during the initial expansion.
b- Find the heat added to the gas during the initial expansion.
c- Find internal-energy change of the gas during the initial expansion.
d- Find the work done during the final cooling;
e- Find the heat added during the final cooling;
F- Find the internal-energy change during the final cooling;
G- Find the internal-energy change during the isothermal compression.
