in closed water bottle system preasure generates due to vaporization of water.

but this process of vaporization stopes when equilibrium is acheved for a perticular temperature.

but in open bottle system equilibrium is NT acheved and hence vapour preasure can NT be measured.

What is the difference between a squirt bottle and a spray bottle?

easy as. A squirt bottle squirts and s spray bottle sprays. How can you not know that!


Why does an empty sealed bottle collapse with altitude?

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.


What happens if you take all the air out of 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.


Why when the air is sucked out a bottle it collapses?

When an empty plastic bottle is left open to the atmosphere the air pressure outside and inside the bottle are in equilibrium (does not always mean they are equal, but in this case they are equal). This means that whatever force exerted by the atmosphere on the outside of the bottle is balanced by a force from the inside of the bottle. When one sucks the air out of the bottle one removes the source of pressure and forces within the bottle. The pressure differential between air outside and inside bottle is enough to cause the bottle to collapse.Note that this will not happen so easily with glass bottles because even when one tries to suck all the air out of them, they also experience a tendency to collapse, but their structure is strong enough to withstand the pressure differences.


What does changing air pressure do to an empty water bottle?

When you pour in the hot water, it takes up all of the space inside the bottle (since it is a fluid). When you pour out the hot water and quickly put on the cap the air pressure inside the bottle is less than the air pressure outside causing the bottle to implode on itself. I'm not really sure about pouring cold water on after, maybe someone knows the answer to that part. But if you try doing it you can probably figure out what the answer is! Actually: When you pour the hot water in, and then out of the bottle the air that rushes in to replace the water is warmed by the water, and the warmed sides of the bottle, causing it to expand and some air leaves the bottle. When you then cap the bottle and let it cool to room temperature the air inside contracts, but because the cap is on no air can get back in to even things out. This causes the pressure inside the bottle to drop. Because the outside air pressure is higher than that inside the bottle, the bottle will chrush in, if it is plastic, until the bottle is small enough that the two pressures are equal. Pouring cold water on the bottle just amplifies the contraction of the air inside the bottle causing an even more pronounced effect. Note that this can be hazardous if you use glass, because the glass will not bend or crush but appear normal until the pressure difference gets to high and the glass simply implodes all at once.

Why does a empty sealed bottle collapse with altitude?

As altitude increases, the air pressure decreases. The air pressure inside the sealed bottle remains constant, creating a pressure difference between the inside and outside of the bottle. This pressure difference causes the higher pressure inside the bottle to push outwards, leading to the bottle collapsing due to the lack of external pressure to balance it.


Why CO2 gas comes out in force when bottles of soda is opened?

The cause is the pressure difference between the gas pressure in the bottle and the atmospheric pressure.


Why does a bottle collapse when it has heated air?

When air inside a bottle is heated, it expands and increases pressure. If the bottle cannot withstand this increased pressure, it will collapse as the hot air cools down and contracts, creating a vacuum. The difference in pressure between the inside and outside of the bottle causes it to collapse.


How does the oxygen being burned in a bottle create vacuum that sucks an egg in?

because there is is a pressure difference between the inside of the bottle and the outside. the pressure is lower in the bottle the egg gets sucked in. when the oxygen is burned there is less matter in the bottle then at first and that results in less pressure[vacuum]


Why will an empty water bottle collapse in a freezer?

When an empty water bottle is placed in a freezer, the air inside the bottle cools down and contracts, creating a lower pressure in the bottle compared to the external pressure. This pressure difference causes the bottle to collapse as the external pressure compresses the bottle inward.


Why was there a sound when a bottle of wine was opened?

The sound results from the difference in air pressure in the bottle as the cork is removed.


Who did the experiment when you crumple a piece of paper inside the opening of a bottle and blow?

It is a common physics experiment where the crumpled paper inside the bottle creates a seal, trapping air. When you blow into the bottle, the air pressure increases, causing the paper to move outward due to the pressure difference between the inside and outside of the bottle. This experiment demonstrates principles of air pressure and pushes the paper out of the bottle.


Why does lotion spill out of bottles in your suitcases when you are on a plane?

When the plane reaches altitude, there is a large pressure difference between the bottle and its surroundings, so they balance.


Can air pressure alone cause a piece of bologna to be pushed into a bottle?

Excluding mechanical force or gravity (small bologna, large mouth bottle), it is only air pressure that pushes a bologna into a bottle. It is the pressure difference from the atmosphere and the lesser pressure (vacuum) in the bottle. There is no such thing as "sucking." It is all about pressure differential.


Why when you suck a air of a bottle it shrinks?

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.


Does the pressure in the ocean change the shape of a glass bottle?

Yes, the pressure in the ocean can potentially change the shape of a glass bottle. The external water pressure increases the deeper you go in the ocean, which can lead to the bottle being compressed or deformed due to the difference in pressure inside and outside the bottle.


What might happen if you prick the balloon in the bottlle balloons experiment?

If you prick the balloon in the bottle balloons experiment, the air trapped inside the balloon will escape, causing the balloon to deflate. This will create a difference in air pressure between the inside and outside of the bottle, potentially leading to air rushing into the bottle to equalize the pressure.
