This is due to condensation. The cold surface of the bottle condenses the water vapor in the air (humidity) into liquid water.
A good experiment to try, when it's really cold outside, is to buy a bottle of bubbles. Blow the bubbles outside and see what happens to them.
Condensation - The surface of the bottle and the air just above it will be cool enough to allow condensation of the water vapor in the air onto the bottle's surface.
Your water bottle contains some air along with the water. The air is warm when you leave the house but it cools off outside. Cooling air contracts. Since the water bottle is sealed air-tight, no new air can get in. The contracting cooling air inside the bottle exerts less internal pressure on the bottle, so the external pressure which remains constant (24 pounds per square inch) will then partially collapse the bottle.
You sshouldnt but, it could be cold and since cold= freezy it would be easier
Yes! If you heat a bottle with hot water, the balloon would grow bigger and bigger while if you put it under cold water, you would find out that the balloon became deflated again.
because it is hot outside so the bottle sweats as it absorbs heat
Did you ever take a cold bottle of coke out of the refrigerator on a hot summer day? Did you ever leave that same bottle of coke on the counter? What did you notice? You noticed water dropplets forming on the outside of the bottle. That is "condensation" when something cold meets something warm. If you go outside on a very cold winter day and breath...your breath comes out looking like steam...that is condensation. When you exhale on a cold window the water dropplets that form on the window - that is condensation
No dog should be left outside, regardless of temperature.
Yes, it is bad. While cold it will not cure properly and you may just end up with a jellified mess.
It would be advised if you do not want to get cold.
That would be a good idea, especially if your house does not get much sunlight. And if it's wintertime, and cold outside, then I would definitely leave the light on.
You can leave your kids outside in the snow for a while to play depending on the temperature and their age. A good way to make sure they're safe playing in the cold is to make sure they're dressed as warmly as possible.

sometimes not in cold weather

leave it outside
it causes condensation
