A sample of an ideal gas in a cylinder of volume 2.65 L at 298 K and 2.80 atm expands to 8.19 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 1.39 atm. In the second step, the gas is heated and allowed to expand against a constant external pressure of 1.39 atm until the final volume is 8.19 L. Calculate the work for path A. W = Calculate the work for path B. W = J J
