Put the balloon in the bottle with the blowing up part out and blow it up in the bottle.
The air alone is not able to blow up a balloon. When air in the bottle is heated with a balloon on top of it, the air expands due to the heat and moves and finds more space. This in turn will blow up the balloon.
because heat expands things... and the heat expands the air in the bottle and the air in the balloon... the only place for the air to go, since it cannot expand the bottle... is out into the balloon, increasing the pressure there and inflating the balloon. :-)
The air in the balloon will have a difficult time expanding to fill the bottle because the bottle is already filled with air at atmospheric pressure, which creates resistance. The pressure inside the balloon needs to overcome the pressure inside the bottle in order for the balloon to expand and fill the bottle.
Because air takes up space. When you attempt to blow up the balloon, you are adding air to the inside of it. But the air between the balloon and the bottle has no place to go. It will only contract so much.
The oxygen is taken out of the bottle so it gets sucked in.
When a bottle-and-balloon system is placed in hot water, the air inside the bottle expands due to an increase in temperature. Since the bottle is sealed off from the outside, the expanding air has nowhere to go, causing the balloon to inflate as a result of the increased pressure inside the bottle.
No, but you can build a snowman. Yes, you can inflate a balloon in a bottle, although it is more difficult than inflating a balloon that is not in a bottle. The only problem that this presents is that it is possible for the balloon to block the opening of the bottle so that air will be trapped between the balloon and the bottle, which would prevent the inflation of the balloon. However, if you use a drinking straw you can create an avenue for air to escape.
it would go in
When you place a balloon in a bottle and then try to blow it up, the air you exhale can't fully inflate the balloon because the bottle's volume restricts the airflow. The pressure inside the bottle increases as you try to blow up the balloon, making it difficult to inflate the balloon fully.
If you filled the bottle with water and then poked the balloon with a pin, I believe it would pierce but not pop it. With the balloon pierced, all you would then have to do is drain the water from the bottle, maneuver the balloon toward its mouth and drain it, and then finish removing the balloon either by fishing or dropping it out of the bottle's mouth.
Yes, if the air pressure in the bottle is higher than the pressure you are exerting to blow up the balloon, it can make it difficult or impossible to blow up the balloon inside the bottle. The higher air pressure in the bottle will resist the expansion of the balloon.
Air inside the bottle expands when the bottle is heated. Some of it leaves the bottle until the pressure of the heated air remaining in the bottle equals the pressure of the air in the room. The balloon is then placed over the neck of the bottle and prevents any more air from entering or leaving the bottle. The air inside the bottle cools to the temperature of the ice water. The cooler air inside the bottle takes less space (volume) than it did when hot, so it sucks the balloon inside the neck of the bottle. Air pressure inside the bottle causes the balloon to stretch and enlarge until the air pressure inside the bottle, including the air in the balloon, has the same pressure as the air in the room.
