It rises until the air it displaces weighs no more than
the balloon and everything hanging from it weighs.
The air density inside a balloon changes as it rises because the hot air inside the hot air balloon is less dense than the air around it causing it to fly since hot air rises. But as it rises it loses its hot air causing it to eventually not be able to fly anymore and come down.
Yes, It is because in a hot air balloon the hot air rises and the cool air falls down.
ahhh hot air?? hot air rissies sooo when you put hot air nto a balloon it evenually rises
the hot air from the heater rises forcing the cooler air out. this makes the balloon go up. this is convection
Relatively hot air balloon are pretty light, and they have a very large balloon which is filled with hot air, which naturally rises, and if you contain enough of it it is enough to lift the balloon.
Hot air rises. As the air in the hot air balloon is made hotter than the surrounding air it rises.
A hot air balloon flies because it is filled with hot air. Hot air rises and causes the balloon to lift from the ground.

Hot air rises. That is how a hot air balloon works.

Because the fire or heating device heats the air in the top section ( the actual balloon ) and hot air rises... so the hot air trapped in the balloon makes the balloon rise :)
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.
The hot air is less dense than the air surrounding the balloon, so it floats in the surrounding air.
When a hot air balloon is filled with the hot air the air around the balloon is a lot denser. So by convection the balloon rises and the less dense air is replaced by dense air underneath it.
because hot air rises
