What is helium percent by volume?
Helium accounts for around 8% of the volume of all matter (baryonic particles) in the universe.
How much helium would it take to lift 2000lbs?
to lift 1 kg or 2 pounds you need 0.16 kg of helium so for 2000 pounds you need 160 kg of helium or 320 pounds at 1 atmosphere
What element has an atomic mass of 4.003?
Helium
If you have a tank that holds volume capacity of thirty gallons how do you convert that to find the volume capacity of helium?
Thirty gallons of anything is thirty gallons. Maybe you're asking about compressing helium, but you need to say what pressure you're using and what temperature, to determine how much helium will fit into a 30 gallon tank.
What is the answer to What did Doctor Bob do with a bunch of sick balloons?
he tried to helium
Why was the discovery of helium unusual?
Because helium was discovered by spectral methods in the Sun.
What has the author I B Whittingham written?
I. B. Whittingham has written: 'S-matrix for broadening of helium spectral lines by helium perturbers' -- subject(s): Helium, Perturbation (Quantum dynamics), S-matrix theory, Spectra, Spectral line broadening
How could scientists know that helium was a different element from any previously discovered?
I believe Helium was discovered by looking at the spectral lines of colour in sunlight. The two variants of helium found blocked out unique and previously unblocked areas of the spectrum. These spectral lines were unique to Helium and as such scientists knew it was unique.
What country was helium discovered in?
The spectral line for helium was first discovered by a French astronomer working in India during a solar eclipse. An English astronomer determine that this spectral line was due to a previously unknown element. An Italian physicist first detected helium on Earth. A Scottish chemist, was the first to isolate helium on Earth. So where was helium discovered? Depending on how you define "discovery" it was discovered in India, France, England, Italy or Scotland.
Which group helium belong?
group 18
To which family do argon and helium belong?
Argon and Helium are part of the noble gasses family.
How can you tell if stars in a visual binary are on the main sequence?
If they are converting hydrogen to helium, then they are on the main sequence. This can be confirmed with a spectral analysis
When helium was discovered?
Helium was discovered in 1868 as a new spectral line in light from the sun by French astronomer Jules Janssen during a total solar eclipse in Guntur, India. In the same year, Norman Lockyer, an English Astronomer concluded that the new spectral line was caused by an element in the Sun unknown on Earth and named it Helium. In 1882, Italian physicist Luigi Palmieri detected helium on Earth for the first time. March 26, 1895 Sir William Ramsay, a Scottish chemist, isolated helium on Earth.
Who was helium discovered by?
In 1868 Jules Janssen and Norman Lockyear discovered spectral lines of an unknown element in Sun - the element was named helium. In 1895 Per Teodor Cleve and Nils Abraham Langled discovered helium in an uranium mineral.
