Helium
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
Balloons are usually filled with helium gas to make them float. Helium is lighter than air and provides the necessary lift for the balloon to float.
helium is less dense than air. :) so helium will float better than air
Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.
Helium balloons float because helium gas is lighter than the surrounding air. This causes the balloon to be buoyant and rise up in the atmosphere.
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
