Any Gas with a lower density than 1.2kg/m^3 will make a balloon rise. However I think you are talking about helium. Gases that are lighter than air like Hydrogen etc
Helium Is the lighter than air gas that is used to fill party balloon's it is an inert gas, that is it doesn't burn unlike Hydrogen which is the gas that was used in the Hindenburg air ship.
Helium is commonly used to fill balloons. It is non-flammable and lighter than air, allowing balloons to float.

Helium gas is commonly used to fill party balloons because it is lighter than air, making the balloons float.
If you want the balloons to float, you would probably use helium.
Helium at room temperature is commonly used to inflate balloons due to its low density, making balloons float.
Helium is commonly used to fill balloons. It is non-flammable and lighter than air, allowing balloons to float.
Helium is typically used to fill airships and balloons due to its low density, which allows them to float in the air.

If you want the balloons to float, you would probably use helium.
Helium gas is most commonly used to fill balloons to make them float. Helium is lighter than air, which causes the balloon to rise and float.
One example of a gas would be helium. Helium is used to fill up balloons and make them float.
Helium at room temperature is commonly used to inflate balloons due to its low density, making balloons float.
Helium is the element commonly used to fill balloons to make them float. It is lighter than air and creates lift within the balloon, causing it to rise.
Hydrogen is not used to inflate hot air balloons. Just regular air is used which is then heated to make the balloon more buoyant as hot air weighs less than cold air. Hence the name hot air balloons.
Helium is a colorless gas that is commonly used to fill balloons to make them float. It is lighter than air and non-flammable, making it safe for use in balloons.
Hot air, hydrogen or helium are lighter than cold air.
