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 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.
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.
Why does a partially inflated weather balloon expand as it rises?
As height is gained the outside air pressure on the balloon is reduced. This reduction allows the gas inside the balloon to expand.
Why does an inflated balloon inflate inside a bell jar?
because outside air is no longer compressing the sides of the balloon, so the pressure outwards is unbalanced and the balloon grows
What is inside the inflated balloon?
Helium goes into a balloon to make it float.

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.

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.

A partially inflated balloon is released from the ground level and becomes larger as it rises in the atmosphere?
It is true that it will become larger as it risses in the atmosphere. This is because the pressure surrounding the balloon decreases, so the pressure inside the balloon wants to equalise with the outside pressure. This causes the balloon to expand as the inside air is trying to get out. That's why things get 'sucked out' of a plane if there if someone opens the door at 30,000 feet, the cabin pressure is trying to equalise by removing the objects and air inside it.
What causes pressure inside a balloon?
hylium (***helium) And actuality the pressure is caused by the elasticity of the balloon itself and don't forget the added pressure of our atmosphere
What causes pressure inside a helium balloon?
The pressure in a container is due to the particles of the gas hitting the inside walls of the container.
Is the pressure of a balloon greater on the inside or outside?
It's greater on the outside until it rises to a point in the atmosphere where the air is very thing. At that point, the pressure inside the balloon is greater which causes it to pop.
What does over-inflated mean on a swan ganz catheter and Where exactly is the inflated balloon and why does the pressure go up off the scale?
your swan ganz catheter is more inside than that required for wedge position, therefore after inflation of the balloon ,the balloon may come in the way of tip of the catheter and it will not show the tracing of the catheter.
Can you measure air pressure in a party balloon?
The air pressure inside the balloon will be slightly higher than outside. This is because the air inside the balloon is slightly compressed by the elasticity of the membrane of the balloon itself. By way of illustration, if you inflate a balloon, don't tie it and just let it go, then to everyones' amusement at parties the balloon flies crazily around the room until it is fully deflated! This fun aspect of balloons occurs as a result of the higher pressure inside the balloon escaping from the balloon to join the air in the room that is at normal pressure. Actually measuring the pressure inside the inflated balloon would require an experiment where the volume of pressurised air in the inflated balloon could be measured by a) measuring the volume of pressurised air inside the balloon by fully immersing the inflated balloon in a measuring receptacle full of water (with normal atmospheric pressure in the room pressing down on the surface of the water) and, then b) measuring the volume that the pressurised airinside the balloon would occupy once outside the balloon at normal atmospheric air pressure by inverting the measuring receptacle full of water (whilst held in a larger shallow tank of water so as to keep the measuring receptacle full of water once inverted - in the usual physics lab manner) and then release the air from the balloon into inverted water-filled measuring receptacle where it would gather in the top of the same. The difference in the two volumes would directly correlate with the difference in air pressure inside and outside the balloon.
