Hot air balloons were invented by three frenchmen named Jacques and Joseph Montgolfier, and Pilatre de Rozier.
As the balloon cools down, the air inside will also cool. This will cause the air pressure inside the balloon to decrease, potentially leading to the balloon descending back to the ground due to the decreased pressure.
When you fill a balloon with air, the air molecules displace the surrounding space inside the balloon, causing the balloon to expand and stretch. The pressure of the air inside the balloon exceeds the pressure outside, creating tension in the balloon material, which keeps it inflated.
It's a gas. The air molecules are free to move around anywhere in the balloon.
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.
Heating the air makes less air take up the same space, so the air inside the balloon is lighter than the surrounding air. The pilot turns off the burner to help the balloon to maintain the current altitude or to descend.
The hot-air balloon was invented in 1783.
God.
hot air balloon
today
no... they invented the hot air balloon and that's all.
The first hot air balloon was invented in Annonay, France by the Montgolfier brothers in 1783.
In the 1740's.
The hot air balloon was invented in 1783 by Joseph and Jacques Montgolfier in France. They made history with their first manned flight in a hot air balloon on November 21, 1783.
The hot air balloon was invented in France. The first manned flight took place in Paris in 1783 by the Montgolfier brothers.
they invented there hot air baloons in France where they grew up..

France, which is not and never will be part of the United States of America, despite the efforts of Marquis de Lafayette! Balloons were invented in France.
