If you pack a bag of potato chips for a snack on a plane

Last updated: 7/28/2022

If you pack a bag of potato chips for a snack on a plane ride, the bag appears to have inflated when you take it out to open. If the initial volume of air in the bag was 380 mL at 760 mm Hg, and the plane is pressurized at 630 mm Hg, what is the final volume (in mL) of the bag? The temperature and the number of gas particles do not change.
