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.
What else can I help you with?
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.

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 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.
Why do we close the mouth of an inflated balloon?
Closing the mouth of an inflated balloon helps to keep the air trapped inside. If the mouth is left open, the air can escape and deflate the balloon. Closing the mouth also helps to create pressure inside the balloon, keeping it inflated.
Why does an inflated balloon stick to a wall?
When an inflated balloon is pressed against a wall, the air inside the balloon gets compressed, creating a higher pressure inside the balloon. This higher pressure forces the balloon to stick to the wall due to the imbalance of pressures pushing against the wall.
What happens to a balloon when you fill it with air?
When you fill a balloon with air, the air molecules displace the surrounding space inside the balloon, causing the balloon to expand and stretch. The pressure of the air inside the balloon exceeds the pressure outside, creating tension in the balloon material, which keeps it inflated.
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.
What would happen if you took an inflated balloon to the top of a mountain?
If you took an inflated balloon to the top of a mountain, the air pressure surrounding the balloon would decrease as you ascend. This would cause the air inside the balloon to expand, potentially leading to the balloon bursting if the pressure differential is too great. Additionally, the lower air pressure at higher altitudes would cause the balloon to appear larger than it would at sea level due to the decreased external pressure pushing against it.
