Ten Facts about Helium
- Helium is the second most abundant element in the universe, and the second lightest element.
- It is estimated that our sun produces 700 million tons of helium per second.
- Helium has the lowest boiling point of all elements—4.2 degrees Kelvin (that -268.8 Celsius)—just 4 degrees above absolute zero.
What is helium facts for kids?
Helium is the only element that does not solidify under ordinary pressures and remains a liquid even at absolute zero. Helium is one of the inert or noble gases. This means that its outside electron shell is filled with electrons. This makes it very unreactive and non-flammable.
What are 3 uses of helium?
Because it is very unreactive, helium is used to provide an inert protective atmosphere for making fibre optics and semiconductors, and for arc welding. Helium is also used to detect leaks, such as in car air-conditioning systems, and because it diffuses quickly it is used to inflate car airbags after impact.
What cool things can helium do?
Its uses include helium party balloons, as a protective inert atmosphere for chemistry storage and reactions, and for cooling superconducting magnets for NMR spectrometers and MRI machines.

Is helium flammable or not?
Perhaps the most familiar use of helium is as a safe, non-flammable gas to fill party and parade balloons. However, helium is a critical component in many fields, including scientific research, medical technology, high-tech manufacturing, space exploration, and national defense.
Is helium rare on Earth?
Helium is the second-most common element in the universe, but it’s comparatively rare on Earth. It also fulfills a surprising role in everything from space exploration to quantum computing.
Does helium make your voice higher?
Most kids would agree: Sucking a lungful of helium out of a balloon makes your voice sound hilarious. But contrary to popular belief, the switch from air to helium gas doesn’t actually increase the pitch of your voice (at least not very much).
Does helium have a smell?
Helium is chemically inert. It has no odor, color or taste. Helium has a boiling point of -452.1 F, and is the only substance that remains fluid at temperatures approaching absolute zero making it the coldest liquefied gas.
Is helium lighter than air?
Helium is less dense than air. Helium has 0.0114 pounds per cubic foot. For a one cubic foot helium filled balloon , gravity pulls the down on the helium with a force of 0.0114 pounds while the air pushes up with a force equal to the weight of the air the helium displaced, or 0.0807 pounds.
Can helium balloons lift a dog?
Jennamarbles uses 72 huge helium balloons to lift her pet marbles off the ground.
Can helium balloons lift a baby?
For a baby, you would need fewer than 4,000 balloons. It would only take four of those to give you the same lift. One balloon that is 30 meters (about 100 feet) in diameter displaces 14,137,000 liters, so it can lift 14,000 kilograms (about 31,000 pounds) — this is roughly the size of a large blimp.
