How do hot air balloons use air to fly?
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
Why do hot-air balloons use fire?
Yes
Why do we use warm air in a hot air balloons?
This is because of convection. Hot air rises and cool air falls which causes the balloon to rise.
Why the hot air balloon needs hot air to make it rise?
Hot air balloons use hot air because hot air rises above cold air. The air inside the balloon is heated above the temperature of the air outside the balloon. The warmer air trapped inside the balloon then causes the balloon to float above the outside colder air.
Where does the hot air balloon energy come from?
Most hot-air balloons use propane (a liquified petroleum gas) as fuel for burners which heat the air in the balloon. The heated air has lower density than the air outside the balloon, which gives it buoyancy and generates lift.
Which gas do you use for hot air balloons?
Hot air is used for hot air balloons.
How do hot air balloons use air to fly?
Hot air balloons use the fact that hot air rises as a way to make balloons fly. When the air inside the balloon is heated, it rises, and this creates lift which is used to make the balloon fly.
What fuel do hot air balloons use?
Fire and, well, hot air.
Why do hot air balloons use hydrogen?
'Hot air' balloons don't use hydrogen. They use hot air. Balloons that use hydrogen are not referred to as 'hot air' balloons. The only balloons that can accurately be referred to as 'hot air' balloons are the members of the balloon population that derive their lift/buoyancy from the presence of hot air. Of course, if a balloon used no hot air, then it could freely be referred to as a 'hydrogen' balloon, a 'helium' balloon, a 'water' balloon, etc., depending in congruent harmony with the nature of whatever substance had been chosen with which to inflate it it in order to maintain its fulsome shape.
How were hot air balloons used by the military?
The first use of hot air balloons was in the American Civil War for surveillance of troop movements.
Do they use fire with hot air balloons?
Yes
Why do hot-air balloons use fire?
Yes
What 2 things that use hot air to rise?
hot-air balloons and birds in flight.
How did they use hot air balloons in the civil war?
bbksu
Do hot air balloons use instrumentation?
yes they use altimeters and gps's
Why is hot air better than helium in hot air balloons?
Hot air balloons use hot air. They have a burner to heat the air. Hydrogen balloons were too dangerous because hydrogen is highly flammable, even static electricity could cause an explosion. Helium is safer because helium is not flammable.
What is the type of gas they use in hot air balloons during 1999?
Hot air balloon pilots use propane to heat their balloons. It's inexpensive, very easy to obtain, and works.
