Starting with 2.50 mol of nitrogen gas (N2) in a container at 1.00 atm pressure and 20.0 °C temperature, a student heats the gas at constant volume with 15.2 kJ of heat, then continues heating while allowing the gas to expand at constant pressure, until it is at twice its original volume.

  1. What is the final temperature of the gas?

  2. How much work was done by the gas?

  3. How much heat was added to the gas while it was expanding?

  4. What is the change in internal energy for the whole process?
