How does the air density inside a balloon change as it rises from the ground to the air?
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.

When does a hot air balloon rise?

Why is a hot air balloon able to lift itself?
because hot air rises
How can a hot air balloon move towards the wind?
