No, I am sorry, but there is no helium inside a hot-air balloon. Instead, there is hot air.
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
There are actually a number of ways to make a balloon lift, without helium. Hydrogen is even less dense than helium (but has the disadvantage of also being highly flammable). And since hot air is less dense than cooler air, you can lift a balloon just by heating air. Since hot air is less expensive than either helium or hydrogen, that is a popular technique.
A balloon rises against gravity because of buoyancy force - the difference in density between the air inside the balloon and the surrounding air creates an upward force. By heating the air inside the balloon (hot air balloon) or by using a gas that is lighter than air (like helium or hydrogen), the balloon becomes less dense and is lifted up.
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! :)
Airships typically run on one of two things: helium or hot air. Helium is a non-flammable gas that provides lift for the airship. Hot air is used in hot air balloons to provide lift by heating the air inside the balloon.
A hot air balloon doesn't contain helium.
Only a hot mixture of the same gases that are in the air you breathe.
A hot air balloon doesn't contain helium or hydrogen.
No, hot air balloons, as the name suggests, contain hot air, not helium.

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.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
A hot air balloon rises due to the principle of buoyancy. As the air inside the balloon is heated, it becomes less dense than the surrounding air, causing the balloon to float upwards. This effect is similar to how a helium balloon rises in the atmosphere.
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.

Balloons are filled with gas (such as helium), or a mixture of gasses (such as air) or hot gasses (such as hot air).Helium.
