Starting with 2.70 mol of N2 gas (assumed to be ideal) in a cylinder at 1.00 atm and 15.0 ∘C, a chemist first heats the gas at constant volume, adding 1.36 × 104 J of heat, then continues heating and allows the gas to expand at constant pressure to twice its original volume.
(a) Calculate the final temperature of the gas
(b) Calculate the amount of work done by the gas.
(c) Calculate the amount of heat added to the gas while it was expanding.
(d) Calculate the change in internal energy of the gas for the whole process.
