A sample of an ideal gas in a cylinder of volume 2.62L at 298K and 2.68atm expands to 8.12L 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 1.19 atm . In the second step, the gas is heated and allowed to expand against a constant external pressure of 1.19 atm until the final volume is 8.12L. Calculate the work for path A. w= Calculate the work for path B. w=
