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.
How long did it take to build the first hot air balloon?
The first hot air balloon was built by the Montgolfier brothers, Joseph-Michel and Jacques-Étienne, in 1782. Their initial experiments began in the early 1780s, culminating in the first successful flight of a balloon made of paper and linen in September 1783. This balloon was launched in Annonay, France, and marked the beginning of human flight in hot air balloons. The entire process from conception to the first flight took about two years.
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.
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.
Is it illegal to build a hot air balloon in your backyard?
If you have children, it should be illegal to have a balloon ready to jump into and take off.
How long did it take to finish the first hot air balloon?
I wish I knew

Do you need a license to build a hot air balloon?
yes
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.

How long does it take to build an air habitat on DragonVale?

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.
