Amonatomic ideal gas undergoes an adiabatic expansion to double its volume. the same final state can be reached by an isobaric expansion followed by an isochoric cooling. what is the ratio of work done by the system between the first and the second processes?

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
