Why do balloons float when you put helium in them?
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)
Why balloons are filled with helium?
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.
Which gas is used to fill the balloons?
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.
Can a blimp filled with helium float in the air?
Yes, it can. Just as helium balloon will.
Which gas is filled in balloon?
The gas is helium or hot air.

How do helium balloons work?
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).

How can balloons float?
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
Can a blimp filled with helium float in the air?
Yes, it can. Just as helium balloon will.
What happens to balloons when they are let go?
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
Which gas is filled in balloon?
The gas is helium or hot air.
Can a helium balloon carry people?
Haven't you heard of balloon boy? LOL! Just kidding! Um no I don't think it's possible sorry.
Where can you buy balloons with helium?
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.
Which has higher density balloon filled with water or helium?
I would say an air filled balloon if you fill it with just plain air. I am basing this on the principle of osmosis and diffusion. A substance such as a gas will travel from an area of increased concentration, such as a balloon filled with helium, to an area od decreased concentration, such as the room the balloon is in. If you fill the balloon with air identicle to that in the surrounding room it negates diffusion.
Is a engine essential to keeping a blimp in the air?
No. helium gas inside the blimp keeps it aloft. Just like a helium makes balloons fly!!
