Why would a balloon inside a bell jar inflate when pressure is decreased within the jar?

The balloon exists in a separate pressure system from the bell jar itself.
As the balloon is open to the surrounding air, the pressure within the balloon is 1 atm (1 atmospheric unit of pressure = 105 Pa).
When pressure is decreased within the jar, the pressure within the jar decreases to a value lower than 1 atm. Therefore, to counter the low pressure created in the jar, the atmospheric air moves into the balloon and pushes the balloon into the jar to attempt to equalize the pressure in the balloon and in the jar. Therefore the balloon inflates.

What has to happen for a balloon to inflate?
The pressure inside the balloon has to exceed the pressure outside the balloon.
What will happen to the pressure inside the balloon as you inflate it?
It will eventually go boom
What causes the air pressure inside an inflated balloon?
The elastic contraction of the rubber in the balloon's membrane causes the pressure in the air inside an inflated balloon. When you inflate a balloon, you have to expand the latex of the balloon, which stretches when filled with air from a pressure of 760 mm Hg to as high as 840 (about 10% higher than standard atmospheric pressure). If you inflate a non-elastic mylar balloon, it takes no effort: the air inside is at the same pressure as the air outside.
Why does an inflated balloon inflate inside a bell jar?
because outside air is no longer compressing the sides of the balloon, so the pressure outwards is unbalanced and the balloon grows
Can a balloon blow itself up?
A balloon can't blow itself up - it can only respond to internal and external forces. For example, if the pressure inside the balloon is greater than the pressure outside the balloon, it will inflate; if the pressure is greater than the balloon is able to stretch, it blows up. Balloons that are filled on the ground, for example, and then released into the sky may eventually blow up as they reach altitudes with lower air pressure.

What would change the size of a balloon?
Increased pressure on the inside, or decreased pressure on the outside.

Is air inside a balloon a element?
In a helium balloon- one that floats and rises to the ceiling it is elemental helium that is used to inflate the balloon. If you just blow into a balloon to inflate it then it is air inside the balloon which is a mixture of gases, principally nitrogen and oxygen (both elements). There are also other gases that are chemical compounds such as carbon dioxide.

Does the pressure inside the bag of balloon increases or decreases?
As the bag of balloon rises, the pressure inside the bag of balloon decreases. Air pressure generally decreases as the altitude increases.
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.
Would throwing a balloon in the air increase the pressure of gas?
The higher the temperature, the higher the pressure and vice versa. When the temperature rises the gas molecules move faster and hit the balloon more often and with more energy.
What is the pressure inside the balloon?
It is the pressure exerted by the elastic balloon envelope and will be higher than the external pressure.
What happens to the atmospheric pressure acting on the balloon as the balloon rises?
due to pressure inside the balloon, will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
