Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
Why do hot air balloons work?
Hot Air Balloons work because of the hot air.The hot air rising stays in the balloon and carries it upward.
Why were hot air balloons made in 1783?
People think that hot air balloons where made for battles.
How do hot air balloons stay in air?
hot air rises
What is something interesting about hot air balloons?
Hot air balloons have a device at the top called a parachute to let the hot air out, controlling their decent.
What last longer helium fill balloon or hot air balloons?
hot air balloons
Why lighter than air balloons fly?
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
Why do balloons float up into the air?
At a hot air balloon festival, hot air balloons slowly fill and then rise majestically in the predawn sky. These hot air balloons fly because of two fundamental principles of physics: the ideal gas law and Archimedes's principle.
Which gas do you use for hot air balloons?
Hot air is used for hot air balloons.

What form is helium?
hot air balloons and balloons
Which gas is used to fill balloons?
Helium is normally used in balloons that float. Helium is the second lightest gas. Hydrogen is lighter, but it is also flammable and thus dangerous.When normal air is used to fill a balloon, the balloon will not be buoyant.If you fill a balloon with air from your lungs, there is a bit more water vapor and a bit more carbon dioxide and a bit less oxygen in the air inside the balloon, but that has a small impact on the buoyancy.The larger balloons that carry people are called hot air balloons because they are filled with hot air. They are buoyant because the hot air is fractionally lighter than normal air but there is a lot of it.Weather balloons and party balloons both use helium gas.As long as the gas plus the balloon is lighter than the air it displaces, the balloon will float in the air.Helium is normally used in balloons that float.
