A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.

Why do hot air balloons float in the air?
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
Can you make a balloon that float in air?
Fill a balloon part way with helium, make an animal out of it and have it float.
Why doesnt a balloon float with your air?
The air from your lungs has the same density as the air in our atmosphere. As a result a balloon inflated by a human using their lungs is unable to float.
How does heilum make a balloon float?
Heilum combined with the light material of the balloon make it as light as air making it float.
What makes a hot air balloon float?
A hot air balloon is able to float because the hot air being released into the balloon is less dense than the colder air surrounding it. Basically, the burner under the hot air balloons fills the balloons with hot air, enabling the balloon to rise through the cooler air outside.
Why can't a hot air balloon float in outer space?
The key word there is float. There is nothing in space for a hot air balloon to float on.

Why do balloons filled with air not float?
Because air is not as dense as helium filed gallons so they won't float
How does heilum make a balloon float?
Heilum combined with the light material of the balloon make it as light as air making it float.
Can dry ice float a hot air balloon?
No. Dry ice is frozen carbon dioxide, which is heavier than air, so wont float a balloon.
If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium gas is lighter than air and hence balloons filled with helium will float in air.

What happens to a hot air balloon that allows it to float through the air?
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
Why does a balloon need hot air?
Hot air is less dense compared to cold air. The heated air in the balloon will rise, making the balloon float in the air.to make it rise.
Does a hot air balloon need heat or cold air to float?
hot
