Helium.
YES!!! However, there is no need to heat the helium. It is a light gas. and it is an inert gas.
Helium is a gas used to inflate lighter than 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 a colorless, odorless, and tasteless inert gas that is used in various applications such as in balloons for parties and in cryogenics for cooling superconducting magnets.
Helium. Hydrogen works too but it tends to blow up. Helium is an inert gas that is very unreactive so it makes the best option.
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.
Foil balloons are filled with helium. Helium is lighter than air and because of this, it is one of the gases that can make a balloon float. It's the preferred gas for these type of balloons because it isn't flammable and is inert, meaning undesired chemical reactions are rare.
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.
element
Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
Helium
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.
