How do hot-air balloons fly?
Hot air balloons can fly because hot air rises. When the air inside the balloon gets hot, it rises above the cooler air around it, and it lifts the balloon and any cargo and passengers with it.
How do hot air balloons return to the ground?
Hot air balloons descend by gradually releasing hot air from the envelope. The pilot controls the descent by manipulating the amount of hot air in the envelope and finding a suitable landing spot. When the balloon reaches the desired altitude for landing, the pilot will release all the remaining hot air and bring the balloon gently back to the ground.
What types of hot air balloons are there?
There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.
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.
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
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 descend?
Hot air balloons descend by releasing hot air from the balloon envelope, causing it to cool down and become denser. This decrease in density causes the balloon to descend slowly until it reaches the ground. Pilots control the rate of descent by manipulating the amount of heat in the balloon.
How can the height be controlled for hot air balloons to land?
There is a valve to release hot air from the top. The amount of hot air you let out from the top is replaced with cooler air from the bottom, causing the balloon to descend.
How do hot-air balloons fly?
Hot air balloons can fly because hot air rises. When the air inside the balloon gets hot, it rises above the cooler air around it, and it lifts the balloon and any cargo and passengers with it.
What is added to balloons and hot air balloons?
Balloons can be filled with air (don't float), or with hydrogen or helium (float because the gas is less dense). Hot air balloons use burners to heat the air so that it becomes slightly less dense than the cooler air around it, providing some lift.

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 is hydrogen used to inflate hot air balloons?
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
What does thrust have to do with hot air balloons?
This may not help, but I didn't think it had ANYTHING to do with hot-air balloons...
