No, I am sorry, but there is no helium inside a hot-air balloon. Instead, there is hot air.

Why are Hot air balloons are filled with air instead of helium?
They are not! The air inside them is trapped in the balloon and heated, expands, becomes less dense and rises therefore pulling the balloon up with it. If helium was used it would explode! :)
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
What last longer helium fill balloon or hot air balloons?
hot air balloons
Why does a balloon float in air?
A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.
What causes hot air balloons to fly?
Usually only balloons that are filled with helium will float. Helium is a gas that is lighter than air, so causes the balloon to fly. Note that if you blow a balloon yourself, it will just float to the ground. There are also hot air balloons in which the air is heated by an on board heater. Hot air, being lighter than cold air, rises and lifts the balloon. When the air cools, unless it is reheated, the balloon descends.
How helium power is in a hot air balloon?
A hot air balloon doesn't contain helium.
Is there more helium or hydrogen in a hot air balloon?
A hot air balloon doesn't contain helium or hydrogen.
Is helium gas in a hot air balloon?
No, hot air balloons, as the name suggests, contain hot air, not helium.
How does a hot air balloon come down?
In rising, a hot air balloon works the same way as a helium balloon : the hot air inside is less dense than the surrounding air outside the balloon. The heavier outside air pushes below the balloon and forces it upward. To come down is easier in a hot air balloon. Unless it is continually reheated, its temperature reverts to that of the surrounding air and the balloon settles back to the Earth under its own weight. Vents that release the heated air (like venting helium in a helium balloon) is an alternative to increase the speed of descent.
Is a hot air balloon filled with helium?
no its filled with hot air from a fire that is lit underneath the balloon.

What gas is used for a hot airballoon?
I am fairly sure that hot air balloons use normal air. They rely more on the idea of bouyancy rather than using specal gases, such as helium. The hot air inside of the balloon is more bouyant than the cold air outside of the balloon. So that makes the balloon ascend till the temperature of the air inside of the balloon is equal to the temperature of the air outside of the balloon. Then as the air inside the balloon gets colder, the balloon starts to descend.
When you heat the air inside a hot air balloon, it rises. Why does this occur?
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
What makes balloons go up?
One of two reasons, either the gas inside the balloon is lighter than the air around it, as would be the case if the balloon was filled with helium, or the gas inside the balloon is hotter than the air around it, as is the case with hot air balloons.

What is the name of the molecules in a hot air balloon?
helium
Why is a high altitude hot air balloon only partially filled?
As it rises, outside air pressure decreases, and the hot air inside expands and fills the balloon. Same thing is true of large helium balloons.
