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.
What else can I help you with?
Why did the inflated balloon move when the air inside it escapes?
When the air inside the balloon escapes, it creates a difference in air pressure between the inside and outside of the balloon. This pressure difference causes the balloon to move in the direction of lower pressure, which is typically outwards.
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.
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.
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
Is the pressure of a balloon greater on the inside or outside?
The pressure of a balloon is greater on the inside because the gas molecules inside the balloon are constantly colliding with the walls of the balloon, creating the pressure that keeps the balloon inflated.

What causes the pressure in a balloon?
The pressure in a balloon is caused by the molecules of the gas inside the balloon colliding with the walls of the balloon. As the molecules collide, they exert a force on the walls, creating pressure. Additionally, the temperature of the gas inside the balloon can also affect the 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.
How does a balloon inflate itself?
A balloon inflates itself when air is blown into it through the opening. The pressure difference between the inside and outside of the balloon causes it to expand and take on its inflated shape.
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.
Why does an inflated balloon kept under the sun burst after some time?
The heat from the sun causes the air molecules inside the balloon to expand, increasing the pressure within the balloon. If the pressure becomes too high, the balloon will burst to release the excess pressure.
Why an inflated balloon gets bigger in hot water?
When the balloon is placed in hot water, the air particles inside the balloon gain energy and move faster, increasing their kinetic energy. This causes them to collide with the walls of the balloon more frequently and with greater force, leading to an increase in pressure inside the balloon. The increased pressure causes the balloon to expand and appear bigger.
Why does a partially inflated weather balloon expand as it rises?
As the weather balloon rises in altitude, the air pressure around it decreases while the pressure inside the balloon remains relatively constant. This pressure difference causes the gas inside the balloon to expand, increasing its volume and size.
