People first used hot air balloons as a means of flying. At the time it was the only way people could fly. Now people do it because they like the feeling of floating through the air, with no wings or engine.

How is a hot balloon lifted into the air?
to make a hot air balloon rise you use hot air
What is the use of air in air balloon?
with out the hot air the balloon would not rise
Why do you use hot air for hot air balloon instead of cool air?
Hot air rises.
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.
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.
Who was the first person to use a hot air balloon?
me
What are the advantage of a hot air balloon?
the mechanical advantage of a hot air balloon is this that we can use it in many good ways like it is for individual flight for every one, and can be use at any time but it depends on the air resistance + gravity because if the gravity is low the hot air balloon would fly far and far in the air and if the gravity is hifgh it would unable to fly and in air resistance if the air is high it would be difficult for a hot air balloon to fly and if air resistance is low it would be difficult for hot air balloon to fly in the air
What does a hot air balloon use to make the balloon go down?
Hot air balloons go down by releasing the hot air in the balloon. Normally you just let the air inside cool and descend slowly. You release hot air only if you wish to descend more quickly.
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 force does a hot air balloon use to keep itself in the air?
air pressure
How do you use trial balloon in a sentence?
The weatherman sent a trial balloon into the air. The director of the hot air balloon event send a trial balloon into the air to test the wind direction.
