What happened to the pressure inside the soda bottle when the cap was removed?

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 when the air in a closed bottle is heated?

What happens when you put a balloon on a water bottle and put it in hot water?

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.

Why do bottles leak in an airplane?

They leak because the pressure inside the bottle is higher than the pressure outside of the bottle. That makes the contents in the bottle want to escape because it wants to equalize the pressure.

Why it is easy to remove air from balloon than from bottle?

This is because the air inside the balloon is a fairly high pressure than the atmospheric pressure air outside the balloon. On the other hand air pressure inside the glass bottle is already equal to the atmospheric pressure so it is difficult to remove air from a glass bottle.

Where is the pressure greatest and the least inside a bottle filled with water?

The pressure at the bottom of the bottle is the greatest. It decreases as the level comes up and is the least at the top.

What is the pressure inside the pressure cooker when closed but no heating will it be equal to atmospheric pressure or not?

The pressure inside will be the same as what the atmospheric pressure was when the lid was closed as long as no heat is added or removed.

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

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.

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.

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]

What causes a plastic bottle when filled with hot water to contract when a lid is placed on the top?

We have to assume that the lid does not allow air to enter the plastic bottle. When the water is hot, the air above the water is also hot. When the air cools down, its volume decreases significantly. This, in turn, causes the pressure in the bottle to decrease such that atmospheric pressureis greater than the pressure inside the bottle. This causes the bottle to contract since the force exerted on the bottle due to atmospheric pressure is greater than the force exerted on the bottle due to the air pressure inside the bottle. The volume of the bottle decreases until the pressure of the air inside becomes equal to atmospheric pressure. The changes in volume, pressure and temperature can be explained by the equation pV=nRT, where p:pressure of gas V:Volume occupied by gas n:number of moles of gas R:molar gas constant T:Thermodynamic temperature of the gas
