- AThe bottle would shrink inward due to increased external pressure.
- BThe bottle would swell outward as the internal pressure becomes relatively higher than the external pressure.
- CNo significant change would occur as the bottle is sealed.
- DThe bottle would become colder due to lower ambient temperature.
The bottle would swell outward. At sea level, the air inside and outside the bottle are in balance. At high altitude, the external atmospheric pressure is lower than at sea level. The relatively higher pressure of the trapped air inside the sealed bottle then pushes outward, causing the bottle to swell.
