A sample of an ideal gas in a cylinder of volume 3.67 L at 298 K and 2.47 atm expands to 8.54 L by two different pathways. Path A is an isothermal, reversible expansion. Path B has two steps. In the first step, the gas is cooled at constant volume to 1.15 atm. In the second step, the gas is heated and allowed to expand against a constant external pressure of 1.15 atm1.15 atm until the final volume is 8.54 L. Calculate work for both paths. Use R = 8.314 constant
