rising air expands then cools and condenses
Air cools as it rises.
it gets warmer as it rises
it gets warmer as it rises
it gets warmer as it rises
it gets warmer as it rises
Warm air rises and then comes down as cool air, and the opposite is also true.
It's the other way round - when air becomes warm, it rises.
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.

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.
