When water freezes it expands in the bottle, and if there is to much pressure on the sides of the bottle it breaks.
It will get cold.
when you but the bottle in hot water the balloon particles push apart and cause expansion
Water, an empty plastic bottle and an air pump.

This answer presumes that "empty" means the bottle has no water in it, but does have air in it.In this case the bottle would collapse (or partly collapse) if the temperature inside the bottle dropped to a lower temperature causing the air inside to shrink, or if the bottle was taken to a place of higher air pressure (such as taking the bottle from a mountain peak to the base of the mountain.The bottle would also collapse at some point of evacuation if "empty" means the bottle was evacuated of water and air. The point of collapse, in this case, would depend on the physical construction of the bottle - ie, whether it was made of steel, plastic or glass
Rather, nothing will happen to the empty water bubble but just making the plastic cold. Actually, it isn't the plastic bottle that is affected, it's only the water that is being affected (if there is any).
an empty water bottle
The water inside the bottle would freeze.
Water expands on freezing, hence will shatter the bottle.
Nothing. The bottle is now truly empty.
full or empty?

simply put water in a bottle and pop it in the freezer
When water freezes it expands in the bottle, and if there is to much pressure on the sides of the bottle it breaks.
The freezer but it depends on how cold you want your water a good trick to get your water colder is to wet a napkin then wrap it around your water bottle and put it in the freezer
The bottle will expand and overflow.
