Question
A 5-mol ideal gas system undergoes an adiabatic free expansion (a rapid expansion into a vacuum), going from an initial volume of 10 L to a final volume of 20 L. How much work is done on the system during this adiabatic free expansion?
Answer
zero

KillGorack 2023-07-09 19:46:18 In an adiabatic free expansion, the gas expands rapidly into a vacuum. Because there is no external pressure for the gas to do work against, the work done on or by the system is zero. This is true regardless of the change in volume, the number of moles of gas, or whether the process is adiabatic or not. In a free expansion, the gas does not push against anything to expand, so no work is done. Therefore, the work done on the system during this adiabatic free expansion is 0 J.
