Because it sends vibrations through the bottle to make a sound
by blowing in it durh!
increases
If the stopper has an airtight seal, the pressure in the bottle will increase, with the same amount of air and water confined to a smaller area.
crumple a small piece of paper into a ball size smaller than the mouth of the empty bottle.hold the empty bottle on its side and place the paper ball just inside its mouth.now try to blow on the ball to force it into the bottle.try the activity with battles of different sizes. when we blow into the mouth of the bottle,the air near the mouth has higher speed. this decreases the pressure there . the air pressure inside the bottle is higher than near the mouth.
Air pressure toward regions of lower air pressure
The air pressure is rising.
the air pressure increases
When we blow the aire increases in that are and the air pressure decreases forcing the thinks to move
The air in the bottle creates a noise.
This is due to pressure. Once you take out all the air, all the air particles are taken out. Therefore, the bottle is vacuumed. The pressure of the air particles outside the bottle are stronger while they bounce against the bottle. Since there is nothing inside the bottle, it is uneven. The bottle then crunches up due to the pressure from the outside. I think that is what happens^ sorry if it isn't the answer you were looking for!
They begin to move quicker
the gathers in the bottle and when its full it must come out and when both directions hit that makes the wliziling sound
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.
The cork over the bottle's neck is going too be pushed by how much air is in the bottle.
When you suck air from a bottle you create a partial vacuum and there is less air pressure in the bottle; but outside there is atmospheric pressure so it tends to collapse the bottle.
It will become vacuum sealed, and opening the bottle will cause a sudden release of low pressure, where higher pressure air from it's surroundings is 'sucked' into the bottle, equalizing the pressure.
Actually, an empty sealed bottle should expand slightly as altitude increases. At the altitude where the bottle is sealed, the air pressure outside the bottle is equal to the air pressure inside the bottle. When the bottle is transported to a higher altitude, the air pressure inside the bottle is greater than the air pressure outside the bottle (In other words: There are more air molecules per unit volume inside the bottle than outside). The increased air pressure inside the bottle relative to the outside pressure causes the bottle to expand slightly. An empty bottle would not collapse as altitude increases.
If the stopper has an airtight seal, the pressure in the bottle will increase, with the same amount of air and water confined to a smaller area.
