Hydrogen was used in blimps and other floating things like weather balloons in the early 1900s. Until the Hindenburg disaster, where a hydrogen filled blimp blew up. This is because hydrogen is flammable.
Now they use helium because it is also lighter than air, so it floats, but also because Helium is not flammable (and is actually flame retardant.)

Does helium contract in cold weather and cause a helium balloon to sink and if warmed will it rise again?
Helium will contract in cold weather, but that may not cause a balloon filled with it to sink since the air will also contract - and by about the same amount - so the relative densities of the helium and the surrounding are would remain about the same and the buoyancy of a helium filled balloon would remain
If a weather balloon with 2-meter diameter at ambient temperature holds 525 grams of helium What type of electronic probe could be used to determine the pressure inside the balloon?

What kind of gas is inside a weather balloon?
Contemporary weather balloons are usually filled with helium. Helium is lighter than air, and this allows the balloon to rise as this gas is lighter than air.Hydrogen would also work as it has a low density, like helium. And hydrogen is a bit cheaper than helium because it can be "made" from water. But hydrogen is flammable or even explosive, and it is generally not used for that reason.
Will a helium balloon float in below freezing weather?
Yes, its to do with the gas density difference of air and helium, rather than the density of gas due to temperature.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air

Used to make a balloon float?
helium gas
Can you use helium in an air balloon not hot air just ordinary party balloons?
yes, but when using Helium you must have the balloon completely sealed and used a mylar material for the balloon as Helium 'leaks-out' of ordinary materials.
How do you use hellium to glue a balloon?
Helium can not glue anything. It may be used to inflate a balloon.
Is a helium balloon a solid?
A helium "balloon" is composed of two parts: the SOLID rubber balloon skin, and the GASeous helium. So the balloon part itself is a solid.
What is another type of hydrogen balloon?
There is the weather balloon, and the zeppelin. Both use Helium, and no longer Hydrogen due to hydrogen's tendency to quickly catch fire.
Will a helium balloon float in below freezing weather?
Yes, its to do with the gas density difference of air and helium, rather than the density of gas due to temperature.
