It's buoyancy - the same as a ship floating in water.
In this case the volume of the balloon must weigh less than an equal volume of air.
(That's done by using a lighter than air gas - hydrogen, helium, or just heated air.)

∙ 15y agoThe pressure on the inside has to be equal on the outside, therefore if you blow up a balloon constantly, the balloon will eventually pop because all that pressure has no way to escape, and then just blows up.

∙ 15y agoA balloon filled with helium gas is less dense than the surrounding atmosphere, which is mostly nitrogen and oxygen (~78% and 13%, I believe). In the same way that a ball filled with air will float to the surface in water, a balloon floats upwards in the Earth's atmosphere.

∙ 15y agoA balloon is typically filled with Helium. The ballon is not typically Helium tight. Helium continues to leak out of the balloon at a very slow rate. If you have a good balloon, it'll stay inflated for a few days before you notice a significant size change.

When an inflated balloon is exposed to cold air?
The volume of the balloon decreases
How an inflated balloon gets larger whwn heated?
The temparature was higher and it caused more air pressure
How long will balloons float filled with exhaled air?
When a balloon is blown up by mouth, it will not float, but fall to the ground. This is because the air inside is the same density as the air outside. For a balloon to float up into the air, it must be inflated with a gas that is lighter than air - such as helium.
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.
Why inflated balloon cannot fit into your bag?
because the air inside the balloon take up the space and it will not allow the balloon to fit in bag
How many air particles are in a balloon?
That depends on how big the balloon is and weather or not it is inflated with air.
How do you describe the motion of air particles inside an inflated balloon?
It is a disordered motion.
What is the difference in the height of the balloon after ten minutes and the height of the balloon after sixty minutes?
There is no difference at all if the balloon is not inflated or inflated with air.
What keeps air balloon inflated?
If you mean a hot air balloon, it is the expansion of the air caused by the propane burner. If you mean any balloon, it is the ability of the material to hold the air or gas inside which keeps it inflated.
When an inflated balloon is exposed to cold air?
The volume of the balloon decreases
Would the air in an inflated balloon be potential energy?
i probably wouldn't say the air had potential energy just that an inflated balloon has potential energy.
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 happens to a balloon when you fill it with air?
It will fill the balloon and make a oval sphere.
Do a balloon keep it's shape because air particles inside it push against the inside surface of the balloon?
Yes.
How does an inflated balloon rise in the air?
It is filled with a gas that is lighter than air.
What occurs to the volume of an inflated balloon when exposed to cold air?
It decreases. The colder air contracts, making the balloon shrink.
Why do you close the mouth of inflated balloon?
The air would escape through the mouth causing the balloon to DEflate
