I don't know if this answer is 100% correct but this is what i know.
If the plastic bottle is capped and then is left in the referigator, the air inside the bottle cools faster than the air outside the bottle. The air pressure inside the bottle also cools down to this reason. The air outside the bottle is warmer than the air inside the bottle. This means that the air outside the bottle is exerting more pressure than the air inside the bottle, and the bottle collapses.

Hi leyalenia . I have No idea weather its correct.
It was the air that shrank, thus reducing its volume.It may seem like the air in your bottle is just empty space, but it is really a mixture of gases.
The force of the individual molecules bouncing off the inside and outside of your bottle is called pressure. When you put your bottle in the freezer, there are more molecules on the outside of the bottle than on the inside, so the pressure outside is greater than the pressure inside the bottle.
The difference in pressure causes the bottle to collapse, because the forces pushing in from the outside are much greater than those pressing out from the inside.
