Helium is an element that is less dense than the air around it. This is because it is sooner on the Periodic Table (BY FAR) than all the other elements such as Nitrogen which is 70% of the air. As you should know, the elements have a weight and volume. Density is weight divided by volume, so elements sooner on the periodic would be less dense being lighter. So, the helium in the balloon and the weight of the balloon are together less than the air around it all, so it floats. Incidentally, balloons filled with air can indeed float, as many ballooning hobbyists know. Air expands as it is heated, and as a result it is less dense than the surrounding air. Balloons filled with hot air will float.
What else can I help you with?
Why do balloons float when you put helium in them?
The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)
Why does a helium filled balloon rise in relation to its density?
I'm not sure I understand the question but here goes: Helium is lighter [less dense] than air, so a helium filled balloon rises because it floats up on the more dense air.
Why does a helium balloon go up?
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.
Why does a helium balloon float up when it is released?
A helium balloon floats up when released because helium is less dense than air. The helium inside the balloon is lighter than the surrounding air, causing it to create a buoyant force that pushes the balloon upward.
What happen when a balloon is filled with helium?
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.
Why is that a big balloon filled with the helium floats?
Helium is lighter than air. hence helium balloon will float in air.
Why a balloon filled with helium floats in air?
Helium is less dense than air
Why will a helium filled balloon will float in air?
A Helium filled baloon floats in air because Helium is lighter than air. Making it rise to the top of it.
Why does a balloon filled with helium rise with a balloon filled with an equal volume of average atmospheric air does not?
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.

Why inside balloon is gas?
Its filled with gas because certain gases(Helium, Hydrogen) are lighter than air so they float. That's why the balloon floats.
Why inside balloon is a gas?
Its filled with gas because certain gases(Helium, Hydrogen) are lighter than air so they float. That's why the balloon floats.
Why is the declaration of independence stored in a hydrogen filled case?
because helium is a source of of air but not exactly air because it has the compounds to push against air to fly up unlike ex. if i filled a balloon with air and one with helium the one with air can floats but goes back down but the on helium floats off because its atoms in the balloon are jumping around and it has sub atomic cells
