If I were to let go of a Helium balloon with a volume of 3 liter at a depth of 10 meters, how do i calculate te time it will take the balloon to reach an altitude of a 100 meters in the air? And what changes if its not helium but hydrogen for instance?

hope anyone can help me with this

Welcome to PF greset,

This smells like homework to me... :wink:
