What is the most common use of helium gas?
Filling balloons
Welding
Lighting
Medical imaging
Helium gas is a non-toxic, inert gas that has low density, low reactivity, and high thermal conductivity. These properties make it an ideal gas for filling balloons, blimps, and other similar objects. When helium is used to fill a balloon, it makes the balloon lighter than air, which causes it to rise and float in the air. Helium is also widely used in many other applications, such as welding, cooling of nuclear reactors, and medical imaging, but the largest and most common use of helium is definitely for filling balloons.
