helium is less dense than air. :) so helium will float better than air
The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)
Hydrogen, until the Hindenburg,then everyone realized that "Hey, Hydrogen isn't that safe to use!"Hot air balloons, you mean?? Just air that is hot.Actual hand balloons and such? Helium or again, just air. Helium floats better because it is lighter than the surrounding air around it. Helium and air are still used in both.
Yes, it can. Just as helium balloon will.
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 :)
Filling a balloon with enough helium for flight takes a lot of helium, hot air balloons only use hot air because it only takes a couple of tanks of propane to heat the air, which is much more cost effective than filling the balloon with helium. Airships use helium because they are used to stay in the air for extended periods of time, so it makes sense to pay for the helium to fill it once, rather than the propane to keep the air hot.

helium balloons get filled with a amount of air in which is called helium it is used to make balloons float around in air. helium is a inert,gaseous element!!!!!yea i kenisha am smartHelium is less dense than air, therefore a helium-filled balloon will float in air.Helium is lighter that air, so it effectively floats on air. As a helium balloon is submerged in air, it rises upwards (like an air filled bubble in water).

Fill two balloons. One with hydrogen gas and the other with helium gas. Allow them to float on a piece of string. Taking a lighted/burning taper/splinter. , and burst the two balloons with the burning splinter. The helium filled balloon will just 'pop' and fall to the ground. The hydrogen filled balloon will 'pop with a flash of flame' So helium ; NO Flame Hydrogen ; A FLASH of FLAME.
Helium is lighter than air and this causes the air to push it up. (just as water pushes up things that are lighter than it i.e. a boat) This is called buoyancy

well it depends what type of balloon it is if it is filled with helium it will float higher and higher until it will pop under the air pressure. but if it a ballon filled with normal air it will just float back down or get blown away if there is wind
they don't, they just give you a high pitched voice
The gas is helium or hot air.
There are several companies that sell balloons wholesale. Balloon Warehouse and Bargain Balloons are just two. One can also purchase balloons at wholesale prices on eBay.
