A cylinder with a piston contains 0.100 mol of nitrogen at 2.00×105 Pa and 320 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 initial compression

B) Find the heat added to the gas during the initial compression

C) Find internal- energy change of the gas during the initial compression

n = 2.58 mol of Hydrogen gas is initially at T = 376 K temperature and pi = 1.88×105 Pa pressure. The gas is then reversibly and isothermally compressed until its pressure reaches pf = 8.78×105 Pa. What is the volume of the gas at the end of the compression process? What would be the temperature of the gas, if the gas was allowed to adiabatically expand back to its original pressure?
