Consider an ideal gas enclosed in a 1.00 L container at an internal pressure of 14.0 atm. Calculate the work, ?, if the gas expands against a constant external pressure of 1.00 atm to a final volume of 14.0 L Now calculate the work done if this process is carried out in two steps. First, let the gas expand against a constant external pressure of 2.80 atm to a volume of 5.00 L. From the end point of step 1, let the gas expand to 14.0 L against a constant external pressure of 1.00 atm.
