Use the following information regarding the initial and final states of a gas:
The initial state of 1 mol of an ideal gas is P1 = 3 atm, V1 = 1 L, and Eint1 = 456 J. The final state is P2 = 2 atm, V2 = 3 L, and Eint2 = 912 J. All the processes are quasi-static. (Provide all answers in Joules) (Note: 1 L atm = 101.325 J)
2) The gas is allowed to expand at constant pressure to a volume of 3 L. It is then cooled at constant volume until its pressure is 2 atm:
a) Show this process on a PV diagram and calculate the work done by the gas.
b) Find the heat added during the process.
