A sealed container holds an ideal gas at a pressure of \(2.0\) atm and temperature \(300\) K, occupying a volume of \(5.0\) L. The gas is heated at constant external pressure of \(2.0\) atm until its temperature reaches \(450\) K, allowing the piston to move.\n\n(a) Calculate the final volume of the gas.\n(b) Determine the work done by the gas during this isobaric expansion. (Give your answer in joules, using \(1\;\text{atm}=1.01325\times10^{5}\;\text{Pa}\).)

Answer Options
