When you suck air out of a bottle, you decrease the air pressure inside the bottle. The higher air pressure outside the bottle then pushes the walls of the bottle inwards, causing it to shrink. This is due to the difference in air pressure inside and outside the bottle.
When the air is removed from a bottle, the external air pressure becomes greater than the pressure inside the bottle, causing the bottle to collapse. This is because the air pressure on the outside is strong enough to compress the bottle's walls, leading to its collapse without the internal pressure to counterbalance it.
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.
The air pressure inside the water bottle helps to maintain its shape and prevent it from collapsing as water is consumed or as external pressure is applied to the bottle. Additionally, the air pressure helps to keep the water inside the bottle from leaking out.
Because it sends vibrations through the bottle to make a sound
As the air inside the sealed bottle is heated, it will expand and increase in pressure. When the air is allowed to cool, it will contract and decrease in pressure. This change in pressure can potentially cause the bottle to deform or even explode if the pressure builds up too much.
A water bottle has air pressure because the air inside is compressed due to the volume of the bottle decreasing as you drink from it. When you open the bottle cap, the compressed air rushes out quickly, causing a hissing sound as it equalizes with the surrounding air pressure.
only after they grow but if they gro to much they might explode
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.
The hypothesis for an egg in a bottle experiment could be that when the fire heats the air inside the bottle, the air expands and escapes. This creates a lower air pressure inside the bottle, allowing the egg to be forced into the bottle due to the higher air pressure outside.
Blowing air towards a bottle can either increase or decrease airflow within the bottle, depending on factors such as the pressure of the blown air and the size of the bottle opening. If the blown air has higher pressure than the air inside the bottle, it may push air into the bottle; conversely, if the blown air has lower pressure, it may draw air out of the bottle.
Heating the air in a closed bottle will increase the temperature of the air, causing the air molecules to move faster and exert more pressure on the walls of the bottle. This increased pressure can lead to the bottle expanding or potentially even bursting if the pressure becomes too high.
