When boarding an airplane you bring a bag of chips. While in flight the bag puffs up, because
A)air pressure in the air-tight bag is greater than cabin air pressure.
B)suction is occurring.
C)air pressure is affected by the Bernoulli principle.
D)all the above
E)none of the above

Question

Quizplus · Accepted Answer

The air pressure in the bag of chips is greater than the cabin air pressure due to the decrease in air pressure at high altitudes. This causes the bag to puff up as the air inside the bag expands. Suction and the Bernoulli principle are not relevant factors in this scenario.
