Question
A sample of an ideal gas in a cylinder of volume 3.42 L at 298 K and 2.63 atm expands to 8.93 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
1.49 atm. In the second step, the gas is heated and allowed to expand against a constant external pressure of 1.49 atm until the
final volume is 8.93 L.
Calculate the work for path A.
W=
Calculate the work for path B.
W =
J
