Answer 2

Answer:

Explanation:

The greater the altitude, the lower the density of the atmosphere. If a light balloon does not change in any way, it will eventually reach a height where the buoyancy related to the air it displaces no longer exceeds the pull of gravity. The balloon stops rising. As balloons rise, air pressure around them diminishes.
