how high does a helium filled baloon float and is it ture that it would get bigger and bigger until it popped?

Answer 1

yes it can pop. the pressure of the atmosphere decreases as the balloon goes higher. as the atmospheric pressure drops the pressure in the balloon can overcome it and the volume increases. but that is not considering any temperature changes inside the closed vessel of the balloon. remember PV = PV

Answer 2

At the point of release, the balloon has a buoyancy given by its weight subtracted from the weight of the air displaced by it. As the balloon rises, the surrounding air becomes progressively less dense, but to some degree the balloon can expand to compensate for this. Once the balloon has reached the limit of its expansion. it cannot rise much further. The limit is typically not enough to cause the balloon to burst, so it will float along, gradually losing helium by diffusion (and descending) until its buoyancy can no longer keep it aloft.

Answer 3

Helium is lighter and less dense than air, so it floats. If you were to inflate a balloon using your mouth it would sink because it is made of the same air as outside the balloon, the weight of the latex makes the balloon sink.

Getting bigger and bigger until it popped? Do you mean as you are filling it, or after tying it off?

Answer 4

Depends on so many things, air pressure being the main one. Yes, it does get bigger as it rises due to the pressure difference between the inside of the balloon and the dropping pressure outside. If you have ever watched weather balloons being launched, you will have noticed that they seem to be only partly filled. As they rise, and the gas inside expands, the balloon fills out. For the balloon to explode is dependent on the material it is made of.

Answer 5

From Uchicago:
Balloons can fly to an altitude of 26 miles (42 kilometers)

Whether the pop or not is dependant on their construction and if they are over-filled. Helium leaks out and they come back done.

;-D Wait! Is that a UFO?

Answer 6

Because Helium is lighter than the air around.Second lightest gas next to hydrogen.
And yes, as it goes up the surrounding air pressure goes down so the the relative air pressure inside the balloon is allowed to expand.

Answer 7

the weight of a certain volume of helium is less that the weight of the same volume of air, thats why a globe of helium floats, its a phenomenom similar as a piece of wood emerging from the bottom of a swiming pool, ok? the principle of arquimidaes.
but as the globe ascends, the pressure of the air becames thiner and thinner. the volumen inside the gloibe increases as the oputside pressure decreases, and the globe gets bigger, until,at the end, it simply explodes.

Answer 8

helium is lighter than air so thats how it floats...and it only gets bigger n bigger the warmer it gets...so usually b4 it got above cloud height it wud pop but if it was to get to the outer reaches of the earths atmosphere it wud still pop coz the cold wud compress the gas n balloon wud pop...i know clever arnt i and im a scouser who wud think a scouser had a brain....haha think b4 u answer that? lmaojust giz 10 points an av it dun wit

Answer 9

It would float up about 5 miles.....then pop. The reason being that down here a colum of air a inch square weighs about 14 lb...or one barr. and that pressure is all around every square inch of the ballon. But most importantly that SAME pressure is INside the ballon. Otherwise it would implode!! Well up there the amount of gas in the ballon remains fairly constant but the outside pressure drops significantly........so the gas in the balloon drops in pressure but in doing so expands rapidly..........balloon pops !! So sorry kid but you aint gonna see mr balloon face again...sob!!!

Answer 10

Yes, that is correct!

I don't know exactly how high it would float. It would depend on the pressure inside the balloon, and the barometric pressure of the area your are at.
