How many helium balloons does it take to lift a kilogram?
To lift about 110 pounds it could take any where from 100 to 150 balloons to lift a person, a lawn chair, food, and many gallons of water. A man by the name of Kent Couch from Oregon demestrated this for us by flying from his home all the way to Idaho. I would'NT try this unless you have a parachute of some kind of device to help you have a better landing. The Balloons could be about the average party balloons (large ones) that are about 11in in diameter. Now remember this is very dangerous and could even be lethal.I hope this helped you.Thanks for looking--Tiana5701
10000000 helium balloons
it took 53 12" helium balloons to lift a pound, you have to add the weight of the string and balloons
depends on how large the balloon is! ;D
you need to give dimensions (volume), find the lift given by one cubic inch of helium and find out from there.
this is a guess i think it would take about 7 with helium in
depends on how large the balloon is/ how light the human is!
Depends on the weight. Check the MythBusters website, they did an experiment on this.
1 cubic meter helium lifts 1 Kg weight at sea level.
A normal helium balloon can lift approximately 14 grams. As a result, lifting 5 pounds (about 2268 grams), would require over 162 balloons. Note, however, that this is an estimate and may vary between different balloon types made by different manufacturers, as well as by how fully the balloon is inflated.
The mass the balloons can lift depends on the mass of the air displaced by the balloons. Mass lift-able + mass of balloons = total mass of air displaced. Mass of balloons = Total Volume X Density of helium Mass of air displaced = Total volume X Density of air. Density of helium = 1.79 X 10^(-4) Kg/m^3 No: 0.1786 kg/m3 (0 °C, 101 kPa) Density of air = 1.2 Kg/m^3 No: dry air has… Read More
they are used in many different types of balloons such as party balloons and hot air balloons.
because so many kids have let go of their helium balloons , so the plantes just sucked in the helium from the balloons and that's why most of the plantes are made of helim :)
It takes about 300 balloons to lift 200 pound man balloon filled with exactly 1 sq ft of helium yields about 28.2g (upward thrust) 453.6 grams/Lb 453.6(1Lb) /28.2= about 16 blns So to get one pound off of the ground it would take about 16 balloons 16x200= 3200 it would take 3200 balloons to lift a 200 lb person....Only hoover not continually rise on account of the uneven weight distribution and the temp differences in… Read More
25 Balloons (Approx.)(I might be wrong as I am not sure)
258 helium filled balloons filled to 34 psi each
Helium is used in cryogenics, in deep-sea breathing systems, to cool superconducting magnets, in helium dating, for inflating balloons, for providing lift in airships and as a protective gas for many industrial uses (such as arc welding and growing silicon wafers). Inhaling a small volume of the gas temporarily changes the timbre and quality of the human voice.
depends how big the helium balloon is and how many
At standard conditions: 22.4 Liters of air weighs approximately 29 grams 22.4 Liters of helium weighs 4 grams 29 grams - 4 grams = 25 grams That means that each 22.4 Liters of helium provides a buoyant force of 25 grams. 22.4 Liters / 25 grams = 0.896 Liters/gram There are 454 grams in 1 pound 454 grams/pound x 0.896 Liters/gram = 407 Liters/pound If you hook 407 1-Liter helium balloons to the 1-pound object… Read More
because heluim a gassic liquid that comprees therefore you can fill many baloons with heluim
By using Boyle's law, you have a total of 1920 L of helium gas at 1atm. If you have 12L of Helium already all you do is subtract 12L from 1920, which gives you 1908L of Helium, and divide 3L from 1908, which gives you 636 balloons. Hope this helps!
Just say you had a bunch of party balloons filled with helium tied to a person how many balloons would it take for a 150lb person to jump like they were on the moon?
well it depends how much the person weighs so do this take the persons weight and multiply it by five the divide it by how many inches the balloon is around then last but not least you add how much time it takes to blow up the balloon (this is because different heilium machines have different presure gages) and there is how many balloons it takes to lift a person off the ground wit regular… Read More
I am not sure which tank size would weigh 135lbs, but a k tank should weigh around that much. A k tank holds 194 cf of helium and will fill about 440 18" mylar balloons or about 48 36" balloons.
At 25 degrees Celsius (77 Fahrenheit) and standard pressure (101.3 kPa) one pound of helium would fill 2768 Liters (731) Gallons It depends on how big you want to fill the balloons, the pressure of the balloons the temperature and a range of other things.
helium or hydrogen
Helium is a stable gas with a density lower than that of air, and thus can be used for many applications such as balloons and other floating instruments.
It takes one Helium Balloon to float a Guinea pig. Guinea pigs are very light.
The answer is actually in your question. Helium is compressed under high pressure so it has a very high density and is surely denser than outside air. That's why it can be filled into a lot of balloons.
How many balloons do you have to pop and breathe in the helium for your voice to stay the way it sounds for ever?
You breathe helium out pretty quickly when you inhale it. In order for the effect to last the rest of your life, you'd need to breathe enough helium to be able to breathe it out for the rest of your life. Unless "the rest of your life" is measured in seconds (a minute or two at the most), this is impossible. If you asphyxiate yourself with helium, your voice will sound the same way forever… Read More
There are many out there, but one of the most common is Helium. Helium balloons float because the helium inside is lighter than air. However, helium is highly flammable and explosive, so be careful when using in experiments.
450 Joules of energy are needed to lift a 15 kilogram mass 3 meters off the ground.
There are many uses (more than just helium balloons) such as arc welding, cooling for nuclear reactors, artificial atmosphere for divers... theres a lot to name.
Helium is used for many different things such as making balloons float to making your voice squeaky. I prefer making your voice squeaky because it's fun.
One cubic foot of helium will lift 28.2 grams at sea level: (n cubic feet)(28.2 grams/cubic feet)(1/448 pounds/gram) = n * .06294 pounds This is a baseline formula, there are many variables that will affect the lift of helium in air such as air temperature, air pressure and humidity.
It depends on the ballon, not the helium. If you have a normal balloon you will be lucky if it lasts a week. If it is one of those big, silver-ish, expensive balloons it will last for many months.
One balloon could do it, if it's big enough and inflated with the right stuff.
assuming that temperature is constant and that we're talking about regular party balloons (a "regular" 2-gram party balloon can hold ~ 16 grams of gas), you would need 6,156 baloons to hold your weight in equilibrium. you would need an amount greater than this to actually lift you (the more extra balloons, the faster the lift), and this is not accounting for the weight of the string. extrapolated from: http://malaysia.answers.yahoo.com/question/index?qid=1005123102737
a big one I know you are perhaps wanting to have fun with these helium balloons, but there is a problem - many escape into the air and eventually bust over the sea where they come down and get mistaken for food by marine animals. Marine animals can not eat rubber and this kills them. Therefore, if at all possible would you please consider using air in your balloons rather than helium.
6 719 174.875 balloons or 6 719 175 balloons for a 100 000 lb house or 45 360 kg home. This was for my grade 12 physics summative. Did pretty well ^^ The answer above adds in the string (7.2 x10^-4 kg for 100 m of fishing wire) , rubber balloon(0.0029 kg) and helium weight, as well as temperature of 20 degrees Celsius and altitude of 0 above sea level. width and height of balloon… Read More
16 if inflated with air or helium. 800 or so if inflated with heroin.
No, many are lighter. Perhaps the most common lighter-than-air gas is helium, which is used to fill party balloons.
Just under 16 cubic feet.
If it takes 20 seconds to inflate a balloon with helium from a tank how many balloons can be inflated in six minutes?
It is; 18 ballons because 18*20 seconds = 6 minutes
The first year Macy's used helium-filled balloons was 1928. The first year they used large, inflated character balloons was 1927, but these were air-filled and didn't contain helium. The 1927 balloons included Felix the Cat, singer/actor Eddie Cantor, a 60-foot tall dinosaur with a group of cavemen, and assorted turkeys, chickens and ducks. The 1928 parade balloons were made of rubberized silk and filled with a mixture of air and helium, allowing for much larger… Read More
there are many different types: hot air balloons, gas balloons, party balloons, weather balloons and many more complex types of balloons.
Helium is less dense than air so if you fill a balloon with it, it floats. This is helpful as it means they don't have to be hung from something. For example, many balloon arrangements you see at parties on tables or in the corner of the room are filled with helium. They sort of stand upright, in a way. However they do need a weight of some sort to stop them floating away! :)
it depends greatly on the type of sugar. Brown sugar will be less than confectioner sugar, but raw sugar will be far less than helium sugar.
None. No compounds of Helium are known. However under some circumstances in glow dischagre tubes unstable molecualr compounds can be created- these are called "excimers". This is why it can be used in hot air balloons, as it can be heated to extreme temperatures, and used for buoyancy, but will not react and cause an explosion, as hydrogen would.
The same reason that makes ships float. The weight of the helium-filled balloon is less than the weight of the air the balloon displaces(=pushes aside), so it'll rise. Unless it pops or leaks, it'll continue to rise until the air around it is so thin that'it'll weigh the same as the balloon. That'll be the "surface" where the balloon will "float" just like a boat. It is lighter than air itself. The mass of 1.0… Read More
Hydrogen combines with oxygen with explosive force in the presence of a spark. Helium is an inert gas that will not burn or explode, so is much safer to use in balloons and air ships instead of hydrogen. The Hindenburg incident is a good example of why not to use hydrogen in a balloon. In the related links box below I posted an article on it. Helium is more chemically stable than hydrogen and will… Read More
Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can explioit these properties. Helium was the first gas used for filling balloons and dirigibles. This application goes on in altitude research and for meteorological balloons. The main use of helium is as an inert protection gas in autogenous welding. Its biggest potential is found in applications at very low… Read More
