Why does the chip bag expand as you go up a mountain?

• There is more air pressure up higher so the particles expand inside the bag.

• There is less air pressure up higher so the particles compress inside the bag.

• There is more air pressure up higher and so the bag wants to reach equilibrium.

• The air is less dense and therefore has less pressure so the particles can expand inside the bag.
