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.)
What else can I help you with?
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
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.
What is the answer for it already has helium but what is it?
The object that already has helium is most likely a helium-filled balloon. Helium is used to inflate balloons as it is lighter than air, causing the balloon to float.
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?
A digital barometer or a pressure transducer could be used to determine the pressure inside the weather balloon. These devices are capable of measuring the pressure exerted by the gas inside the balloon and can provide accurate readings.
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.

What type of gas is used in balloon vendor?
Helium gas is commonly used in balloons sold by vendors to make them float.
Does a hot air balloon have helium inside it?
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
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.
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.
When a gas like helium is used to fill balloons it does what and takes the shape of the balloon?
When helium is used to fill a balloon, it expands to fill the space inside the balloon due to its low density. The helium gas takes the shape of the balloon because it moves and distributes evenly throughout the balloon's interior.
