What happen to the pressure in the balloon when it is inflated?
When a balloon is inflated, the pressure inside the balloon increases. This is because as the balloon expands, the air molecules become more tightly packed together, increasing the pressure. The pressure remains higher inside the balloon until the balloon is stretched to its maximum capacity.
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.
How could you use an inflated ballon to show that decreasing the volume of a fixed mass of air increases its air pressure?
If you decrease the volume of a fixed mass of air inside a balloon by squeezing it, the molecules inside become more crowded, leading to an increase in air pressure. You can demonstrate this by inflating a balloon and then squeezing it - the balloon will become harder as the volume decreases, showing an increase in air pressure.
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 partially inflated balloon expand as it rises?
As the balloon rises, the air pressure outside the balloon decreases while the air pressure inside the balloon stays the same. This causes the balloon to expand because the higher pressure inside the balloon pushes against the lower pressure outside.
How could you show an inflated balloon to show the decreasing the volume of a fixed mass of air increases its pressure?
You could do this by applying pressure to the balloon, you'll notice that as it get's smaller from getting squeezed it becomes harder to compress, because of the higher pressure.

Is pressure in a balloon less than atmospheric pressure?
Yes, the pressure inside a balloon is typically slightly higher than atmospheric pressure to keep the balloon inflated. When a balloon is fully inflated, the pressure inside the balloon is balanced by the tension in the balloon's material, which allows it to maintain its shape.
Why does a balloon remain inflated?
A balloon remains inflated because the pressure of the air or gas inside the balloon is greater than the pressure of the air outside the balloon. This creates a force that keeps the rubber surface of the balloon stretched tight, preventing it from collapsing.
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.
Explain why atmospheric pressure does not burst an inflated balloon?
An inflated balloon is made of elastic material that can expand without bursting when subjected to increased pressure, such as atmospheric pressure. The elasticity of the balloon allows it to stretch and accommodate the higher pressure while retaining its shape. Additionally, the pressure inside the balloon may equalize with the atmospheric pressure, preventing it from bursting.
What are the molecular forces keeping a balloon inflated?
The gas molecules inside the balloon collide with the walls of the balloon, creating pressure that pushes against the balloon's surface and keeps it inflated. This is due to the kinetic energy of the gas molecules in constant motion.
Why is the balloon inflated and staying that way?
The balloon is inflated and stays that way because it is filled with a gas, such as helium or air, that is less dense than the surrounding air. This causes the balloon to float and maintain its inflated shape due to the difference in pressure inside and outside the balloon.
