Why and how does a hot air balloon fly?
Air expands when it is heated. This makes it less dense than colder air. Hence, it has buoyancy, and tends to rise. If it is trapped in a balloon, it can take the balloon up with it, along with things attached to the balloon, as long as the buoyancy of the balloon exceeds the attached weight.
Where does air go in a balloon?
When you inflate a balloon, the air goes inside the balloon and fills it up. The air molecules push against the walls of the balloon, causing it to expand and take on its inflated shape.
Why does a hot air balloon need flame in order to take off?
A hot air balloon needs a flame to heat the air inside the balloon, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to float upwards. Without the flame, the air inside the balloon would cool down and the balloon would descend.
Why does a hot air balloon float in air?
A hot air balloon floats in the air because the air inside the balloon is heated, becoming less dense than the surrounding air. This creates a buoyant force that lifts the balloon. As long as the air inside the balloon remains hotter than the surrounding air, the balloon will continue to float.
What keeps air balloon inflated?
If you mean a hot air balloon, it is the expansion of the air caused by the propane burner. If you mean any balloon, it is the ability of the material to hold the air or gas inside which keeps it inflated.
How long did it take to build the first hotair balloon?
it took about a year for the first hot air balloon to be made.
How long did it take to finish the first hot air balloon?
I wish I knew

How long would it take to fly in a hot air balloon from one side of the USA to the other?
to fly that far in a hot air balloon it would take up to at least over 15-30 days but that also depends on how fast you get the hot air balloon to fly and if you stay straight on course
How long can a hot air balloon stay up?
As long as they have flue to heat the balloon.
Where does air go in a balloon?
When you inflate a balloon, the air goes inside the balloon and fills it up. The air molecules push against the walls of the balloon, causing it to expand and take on its inflated shape.
Why does air in a balloon take up all the space in the balloon?
It's a gas. The air molecules are free to move around anywhere in the balloon.
What time fly hot air balloon?
i think it takes a long time for a hot air balloon to fly
Will a long balloon or a round balloon hold more air than the other?
A long balloon typically holds more air than a round balloon due to its shape and design, which allows for increased volume capacity. The elongated shape of a long balloon allows it to expand more when filled with air compared to a round balloon.
How old do you have to be to go on a hot air balloon?
Parents are free to take children of any age on a hot air balloon.
What will happen if you inflate a balloon with warm air and take it to a cold place?
The air inside cools. Cool air shrinks. The balloon gets smaller.
