Question

An unopened bag of chips expanding as one drives up a mountain is a good example of how volume

Answer 1

An unopened bag of chips expanding as one drives up a mountain is a good example of how volume depends on the pressure. In fact, in the mountains the atmospheric pressure (that acts outside the bag) is lower than the pressure at sea level (because of the higher altitude). Boyle's law states that for a perfect gas, if the temperature is constant the product between the pressure p and the volume V of the gas is constant:

`pV=k`
Therefore, if p is lower, the volume V increases, and this is why the bag expands.

Answer 2

a good example of an unopened bag of chips expanding as one drives up a mountain is how volume increases when pressure decreases.

Step-by-step explanation:

Say there is a unopened bag with some food in it (besides chips), and it is the same for a mountain, the pressure is decreasing while while the volume is increasing, like the smell of cake or your favorite food is decreasing/disappearing but the smell of nothing is increasing (that is how I think of it) I hope this helps!!!
