As the air in the balloon is heated from the flames, the air becomes lighter. So much lighter than the surrounding air that the balloon eventually rises from the light air in it.
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.
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 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.

Hot air rises. That is how a hot air balloon works.
Hot air rises.
Yes, It is because in a hot air balloon the hot air rises and the cool air falls down.

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.
