A 5.0-mol ideal gas system undergoes an adiabatic free expansion (a rapid expansion into a vacuum),going from an initial volume of 20 L to a final volume of 30 L.How much work is done on the system during this adiabatic free expansion?

Question

Quizplus · Accepted Answer

Adiabatic process means no heat exchange occurs between the system and the surroundings. Hence, there is no change in internal energy and no work is done on the system. Therefore, the correct choice is "zero".
