A cylinder fitted with a piston contains 9.04 L of a gas at a pressure of 4.89 atm. The entire apparatus is contained in a water bath to maintain a constant temperature of 25 °C. The piston is released and the gas expands until the pressure inside the cylinder equals the atmospheric pressure outside, which is 1.00 atm. Assume ideal gas behavior and calculate the amount of work done by the gas as it expands at constant temperature.
