If it's a light balloon, it keeps going up, into thinner and thinner atmosphere, until the pressure inside the balloon is so much greater that the pressure outsize , and then it pops.
you will probably be fine as long as it is not giant
The volume of the balloon will decrease when taken outside on a cold winter day. This is because the cold temperature causes the air inside the balloon to contract, making it occupy less space.
The balloon will either float or pop
The balloon expands.
When you leave a balloon in the freezer, the air inside it will cool and contract, causing the balloon to shrink in size. This happens because the volume of gases decreases when they are cooled, causing the balloon to deflate.
When you release a balloon with air in it, the air inside the balloon is pushed out, causing the balloon to fly through the air. This happens because the air being forced out creates a force in the opposite direction, propelling the balloon forward.
it sinks
