Answer 2

Answer:

Therefore the minimum work done is when the external pressure is 0, which is the case under vacuum. This would mean that the work done under vacuum is 0. ... Therefore when the external pressure is 0 there is nothing for the piston to push against, because there is no opposing force, no work is done by the system.
