Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
Helium is used in balloons instead of hydrogen because it is non-flammable. Hydrogen is flammable and can be dangerous, while helium is inert and poses less of a fire risk. Additionally, helium is less dense than air, providing better lift for balloons.
Helium is used instead of hydrogen in balloons because it is non-flammable, while hydrogen is highly flammable. This makes helium a safer option for filling balloons to prevent any potential fire hazards. Additionally, helium is also lighter than air, allowing balloons to float easily.
Helium is used instead of hydrogen for balloons because it is non-flammable, whereas hydrogen is highly flammable. This reduces the safety risk associated with using hydrogen in balloons. Additionally, helium is more abundant in nature and does not react with other substances, making it a safer and more practical choice for filling balloons.
Helium - it's less reactive.
Because helium is lighter
Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Helium balloons are safer than hydrogen balloons because helium is non-flammable, while hydrogen is highly flammable. Helium balloons are commonly used for celebrations and decorations, while hydrogen balloons are less common due to safety concerns. Helium is also lighter than air, making helium balloons float, while hydrogen is even lighter but poses a greater risk of combustion.
Two of the gases that are used to fly balloons are Hydrogen and Helium. Helium is the preferred gas because Hydrogen is very explosive. The Hindenburg disaster was caused by the ignition of the Hydrogen gas that filled it.
Hydrogen, until the Hindenburg,then everyone realized that "Hey, Hydrogen isn't that safe to use!"Hot air balloons, you mean?? Just air that is hot.Actual hand balloons and such? Helium or again, just air. Helium floats better because it is lighter than the surrounding air around it. Helium and air are still used in both.
Helium is a gas used to inflate lighter than air balloons.
