The air is made up of different elements, such a oxygen, carbon dioxide, nitrogen and argon. On the Periodic Table, you can see that the relative Atomic Mass is bigger for these elements that that of helium. Relative atomic mass is not the actual weight of the atom, that would be too hard to find. Therefore scientists use this to show how big some atoms are compared to others.
I', unsure, but I think the helium atom has an RAM of 2, and oxygen for example has a RAM of 16.
Therefore, helium is lighter.
That's why balloons float. How super.
Helium is lighter than air
yes. helium is lighter than earth or even air.
Helium is lighter than air. so balloons filled with helium will float in air
Helium is lighter than air.
Because helium is lighter than air.
Hot air, hydrogen or helium are lighter than cold air.
Helium is lighter than air. So helium balloon rises in air.
No. Helium is lighter than air
its the 2nd element on the periodic table and it makes things lighter, such as helium balloons, which float as helium is lighter than air
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
Helium is lighter than air. So balloons or air ships filled with helium will float.
Helium is lighter than air. hence helium balloon will float in air.
