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.
a balloon float on water
Fill a balloon part way with helium, make an animal out of it and have it float.
Heilum combined with the light material of the balloon make it as light as air making it float.
Helium goes into a balloon to make it float.
because helium has less density

The key word there is float. There is nothing in space for a hot air balloon to float on.
yes
Heilum combined with the light material of the balloon make it as light as air making it float.
The balloon will either float or pop
Helium goes into a balloon to make it float.
because helium has less density
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
gas
Helium!
When a light gas like heliumis placed in a balloon, it will float.
