Helium is commonly used to fill balloons. It is non-flammable and lighter than air, allowing balloons to float.
Helium is a gas used to inflate lighter than air balloons.
Helium is typically used to fill airships and balloons due to its low density, which allows them to float in the air.
Gases used are: air (and hot air), helium.
Helium (Hydrogen could also be used but this is flamable). Not some balloons are also kept aloft using hot air.
The element used is called neon.The element used is called neon.
Helium gas , because helium is the most inert element of all, and does NOT ignite, and allows balloons to float. If carbon dioxide was used, then the balloons would fall to the floor. Hydrogen is NOT used , because it is flammable and explosive, when mixed with air.
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
