Helium is very dangerous. It can easily ignite in the time of fire. So hot air is more preferable than Helium.
-----------------
Helium is very safe to use as it is non-flammable, however, it is far more expensive than hot air.

When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
Why is helium better than hydrogen in hot air balloons?
Hot air balloons use hot air. They have a burner to heat the air. Hydrogen balloons were too dangerous because hydrogen is highly flammable, even static electricity could cause an explosion. Helium is safer because helium is not flammable.
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.
is helium used in air balloons?
It can be, but usually not. Helium is a bit expensive, and it'd cost too much for most balloonists to use it. It's cheaper to use a hot air balloon. helium is lighter than air. hence balloons filled will helium will float in air.
Something you can fill a balloon with?
Balloons are filled with gas (such as helium), or a mixture of gasses (such as air) or hot gasses (such as hot air).Helium.
Why is hot air better than helium in hot air balloons?
Hot air balloons use hot air. They have a burner to heat the air. Hydrogen balloons were too dangerous because hydrogen is highly flammable, even static electricity could cause an explosion. Helium is safer because helium is not flammable.
What is the difference between a helium balloon and a hot air balloon?
A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift

When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
Does a hot air balloon have helium inside it?
No, I am sorry, but there is no helium inside a hot-air balloon. Instead, there is hot air.
Is helium gas in a hot air balloon?
No, hot air balloons, as the name suggests, contain hot air, not helium.
How helium power is in a hot air balloon?
A hot air balloon doesn't contain helium.

What gases lift a balloon into the air?
Anything less dense than air (hydrogen, helium, hot air).
Why do helium and hot air balloon's rise?
Because helium is less dense than air, so it rises. Hot air balloons rise because heated air from the burner becomes less dense and therefore rises.
