What is the filling gas of holiday balloons?
Hydrogen can be used as a filling gas for holiday balloons. However, because hydrogen is flammable and explosive, helium is also useful.
1895, W. Ramsey of Britain discovered a very light gas, which is the least active element, so it was called "inert gas" and named "helium". 1.75m3 helium weight1.75n, slightly heavier than hydrogen. Although it is expensive to fill the balloon with helium, it is safe and reliable, and will not catch fire and explode. Helium is the most ideal gas for inflatable balloons.
