A sample of an ideal gas in a cylinder of volume 4.41 L at 298 K and 2.14 atm expands to 7.23 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 1.38 atm. In the second step, the gas is heated and allowed to expand against a constant external pressure of 1.38 atm until the final volume is 7.23 L. Calculate the work for path A. w = J Calculate the work for path B. w = J
