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 else can I help you with?
What will happen to the pressure inside the balloon as you inflate it?
The pressure inside the balloon will increase as you inflate it because the volume of the air is being decreased as more air is added, leading to a higher concentration of air molecules in the same space. This results in an increase in pressure.
Why does an inflated balloon inflate inside a bell jar?
An inflated balloon will inflate inside a bell jar because the air pressure outside the balloon is reduced when the bell jar is sealed. This creates a pressure difference between the inside and outside of the balloon, causing the air inside the balloon to expand and inflate it.
What happens to a ballon when you inflate it?
When you inflate a balloon, you are adding air to it which increases the pressure inside. The pressure from the air molecules pushes against the elastic walls of the balloon, causing it to expand and inflate.
Why does a balloon inflate when it gets heated up by a hair dryer?
Heating the air inside the balloon causes the air molecules to move faster and spread out, creating higher pressure inside the balloon than outside. This pressure difference causes the balloon to expand and inflate.
Why does a balloon inflate on blowing air in it?
When you blow air into a balloon, you increase the pressure of the air inside the balloon. This higher pressure pushes against the walls of the balloon, causing it to expand and inflate. The elastic material of the balloon stretches to accommodate the increased volume of air.

What has to happen for a balloon to inflate?
A balloon inflates when it is filled with a gas, such as helium or air, creating pressure inside the balloon which causes it to expand. The gas molecules inside the balloon push against the walls, causing it to stretch and increase in size.
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 a balloon inflate when held in hot water?
When a balloon is held in hot water, the air inside the balloon heats up, causing the air molecules to move faster and spread out. This increases the pressure inside the balloon, pushing against the flexible walls and causing the balloon to inflate.
What would change the size of a balloon?
Increased pressure on the inside, or decreased pressure on the outside.
How do you inflate a balloon by using science?
You can inflate a balloon by using the principles of gas expansion. When you blow air into a balloon or fill it with helium, the gas molecules inside the balloon move faster and spread out, causing the balloon to expand and increase in volume. This increase in volume creates pressure inside the balloon, making it appear inflated.
What causes the balloon to expand when heated?
Heating the air inside the balloon causes the air molecules to move faster and spread out, increasing the pressure inside the balloon. This increase in pressure pushes against the balloon's walls, causing it to expand and inflate.
What happens to a balloon when pressure becomes less?
When the internal pressure in a balloon falls, the balloon get smaller and less buoyant.
