A gas is allowed to expand at constant pressure until it reaches its final volume. It is then cooled at constant volume until it reaches its final pressure. The initial state of 1.00 mol of a dilute gas is P1 = 2.94 atm, V1 = 1.01 L, and Eint 1 = 438 J, and its final state is P2 = 2.00 atm, V2 = 3.03 L, and Eint 2 = 964 J.

Calculate the work done by the gas.

Find the heat absorbed by the gas during this process.
