Question
A sample of an ideal gas in a cylinder of volume 2.99 L at 298 K and 2.16 atm expands to 7.00 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
1.17 atm. In the second step, the gas is heated and allowed to expand against a constant external pressure of 1.17 atm until the
final volume is 7.00 L.
Calculate the work for path A.
W =
-44.6
W =
Incorrect
Calculate the work for path B.
-474.06
