The gas helium is less dense than the nitrogen-oxygen mix of atmospheric air. So a balloon filled to the same pressure (or even higher) will have a lower density than the air around it, which will displace it (flow under it), forcing it upward. The balloon will rise until the combined weight of the helium and the balloon are the same average weight (density) as the surrounding air. Long before it reaches that altitude, a normal balloon will begin to expand and will usually pop (at an altitude of a few hundred to a few thousand feet).
Helium molecules are lighter than most air molecules in the atmosphere (mostly nitrogen and oxygen) therefore they are prone to rise while heavier molecules move downward.
What else can I help you with?
Does a balloon float or sink on water and why?
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
What happens when you stick a balloon to glass will it float?
When you stick a balloon to glass, it will not float on its own. The balloon will stick to the glass due to static electricity generated when rubbing the balloon against your hair or clothes. The balloon's ability to float is determined by the gas inside the balloon and the upward force it creates, not by sticking it to a surface.
Can you make a balloon that float in air?
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
What must happen for a balloon to float in the air?
For a balloon to float in the air, it must be filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
How does heilum make a balloon float?
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
Does a balloon float or sink on water and why?
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
Does a balloon float?
yes
What happens when you stick a balloon to glass will it float?

Can you make a balloon that float in air?
Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.
What happens when you release a balloon on water?
The balloon will either float or pop
What must happen for a balloon to float in the air?
For a balloon to float in the air, it must be filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
Why can't a hot air balloon float in outer space?
A hot air balloon requires air to generate lift. In outer space, there is no air or atmosphere, so there is nothing for the hot air balloon to displace to generate lift, causing it to be unable to float.
How does heilum make a balloon float?
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
What makes a balloon float on water?
A balloon filled with a gas that is less dense than water, such as helium or hydrogen, will float on water due to the buoyant force acting on it. The gas inside the balloon displaces an amount of water equal in weight to the balloon, causing it to float.
What makes a party balloon float?
Helium!
Is there something else to float a balloon?
gas
Why doesnt a balloon float with your air?
A balloon does not float with your breath because the air you blow into it is denser than the surrounding air. To make a balloon float, you need to use a lighter gas, such as helium, which is less dense than the surrounding air and creates enough lift to keep the balloon suspended.
