Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.
Helium.
Hot air balloons are typically filled with heated air, which is lighter than the surrounding air and provides lift. Some balloons may also use helium or hydrogen gas for buoyancy, but hot air is the most commonly used lifting gas for traditional hot air balloons.
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 the noble gas used in party balloons and weather balloons because it is lighter than air. Its low density makes it ideal for filling balloons as it provides buoyancy without adding much weight.
Hot air balloons typically use propane gas as a fuel source for the burner that heats the air inside the balloon envelope. The propane is burned to heat the air, which causes the balloon to rise.
Helium gas is commonly used to fill party balloons because it is lighter than air, making the balloons float.
Helium is a gas used to inflate lighter than air balloons.
Helium gas is commonly used to fly balloons due to its lighter-than-air properties. It is non-flammable and safe for use in balloons to provide the lift needed for them to float in the air.
Hot air balloons are typically filled with hot air, rather than a gas, in order to make them buoyant and rise in the air. The air inside the balloon is heated by a burner attached to the basket, which causes the balloon to lift off the ground.
When tires or balloons are filled with gas or air, they are said to be in an inflated state.
