If I had a helium balloon and I let it go,how high would it go?

Question

I mean outside,(that might sound obvious but there are ppl that would give silly answers)

Answer 1

mr Mills has the correct concept but note. IF balloon did not burst it might go up and down until density less than exceeded support supplied by atmosphere. But note if balloon was inflated at top of montain it would rise above that. hence ht reached dependent upon height released. Also note weather balloons are only partially inflated when they are released. They can reach 10's of thousands of feet.

Answer 2

Good question. If the balloon is vented so that gas can escape when its pressure exceeds the surrounding pressure, then at first glance, there's no limit - helium will always be less dense than the surrounding atmosphere and so produce lift.
However, the lift gets smaller and smaller as the density of both the air and the helium decrease as pressure falls. At some point, the declining lift will just equal the weight of the balloon fabric, and so it stops rising. You'd need more detail to work out the height at which this happens.

Answer 3

I would guess that they might rise as high as 2 or 3 km but it really depends on the size and material that the balloon is made from. A normal balloon made from latex will rise until the pressure drop causes it to expand sufficiently to burst. Mylar balloons are often used for helium because latex is porous to Helium. Mylar will not stretch so will probably not go as high.

Answer 4

What happens is: as they rise up, the air becomes thinner and the balloon expands, this makes the rubber more porous and some of the helium escapes. The balloon can then no longer support it's own weight and it sinks to earth. Max height at a guess, would be about 3000 feet.

Answer 5

Good answers. A well made balloon can reach 10s of thousands of feet. (The first man in space, technically, was Joesph Kittinger, who in 1960 rode a helium balloon to 103K feet, then jumped. Space technically starts at 100K feet.)

You're normal helium balloon will only go up a couple of thousand feet.

Answer 6

The ballon will climb into the atmosphere as per the Archimede Principle of buoyancy.

It wll climb until the energy per Unit volume of the Ballon will exceed the Gravity energy per Unit volume surrounding the ballon.At that point if the structure of the balloon is not strong enough it will explode.

Answer 7

depends on the amount of helium you filled in the balloon

Answer 8

They finally end up in the tree in my returned backyard. heavily, we had a balloon land in the tree in my returned backyard. It became into from an consumer-friendly college in Mississippi and that's a number of hundred miles far flung from me.

Answer 9

It would go as high as its volume (increasing) and decreasing pressure (to equal the outside atmospheric pressure also decreasing), will allow, before bursting.

Answer 10

it depends on its size but a few hundred feet it would get larger due to the increase in pressure and finally burst.
