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.
Is pressure in a balloon less than atmospheric pressure?
No, the pressure of the balloon is more than the atmospheric pressure because the gasses in the balloon are compressed by the stretched material.
What causes the pressure in a balloon?
The elastic property of the balloon. The balloon stretches when inflated, and squeezes the gas filling the balloon.
Why does a partially inflated balloon expand as it rises?
The pressure in the balloon stays the same, but the pressure outside drops as the altitude increases. And as the outside pressure drops, the balloon expands.
What are the molecular forces keeping a balloon inflated?
What keep balloon inflated is not the molecular forces but the kinetics energy of the gas molecules made the molecules to bump and create the pressure inside the balloon.
What would be the length of the arrows if the balloon were inflated more?
The length would stay the same as the pressure inside the balloon equals the atmospheric pressure.
Why do balloons expand as they rise through the troposphere?
The ballon contains a fixed amount of gas producing internal pressure. At the surface, this pressure equals the surface atmospheric pressure. As the balloon rises, the atmospheric pressure drops, allowing the balloon to expand, keeping the internal pressure and external pressure equal. If the balloon is fully inflated at the surface it will burst at higher altitude.

What does the balloon barometer measure?
A balloon barometer measures atmospheric pressure.

How would you demonstrate the presence of atmospheric pressure?
Suck the air out of a container and watch it being crushed. Look at a balloon. Its round shape tells you that the pressure (atmospheric) from outside acts equally from all directions. Now take that balloon up a mountain and watch the balloon get bigger. There is less atmospheric pressure acting on the outside of the balloon the higher you go so the pressure inside the balloon makes the balloon bigger.
Why inflated balloon burst if press it hard?
An inflated balloon bursts if it is pressed hard because the molecules inside the balloon squeeze when it is pressed hard and air exerts pressure so the balloon bursts and let the air molecules escape from the balloon.
What would cause a inflated balloon to become larger?
Changes in air pressure
What would happen if you inflated a balloon on the moon?
Since there is no external pressure to counteract the internal gas pressure, the gas would expand until the balloon burst.
