Homework Help: Helium balloon in water and air

  1. Apr 28, 2008 #1
    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
