A cylinder with a piston contains 0.160 mol of nitrogen at 1.80×105 Pa and 310 K . The nitrogen may be treated as an ideal gas. The gas is first compressed isobarically to half its original volume. It then expands adiabatically back to its original volume, and finally it is heated isochorically to its original pressure.

a.) Find the work done by the gas during the adiabatic expansion.

b.) Find the heat added to the gas during the adiabatic expansion.

c.) Find the internal-energy change of the gas during the adiabatic expansion.
