Helium in sentence

102 examples of Helium in a sentence

In extreme contrast to the million year transformation of hydrogen to helium, the creation of the heaviest elements in a supernova takes place in only seconds.

So there are two compartments here, one with air and then one with helium.

After about a few minutes, there was hydrogen and helium in the universe.

The universe was about 75 percent hydrogen, 25 percent helium.

After about 400 million years, the first stars formed, and that hydrogen, that helium, then began to cook into the heavier elements.

And that is that every minute, 400 pounds of hydrogen and almost seven pounds of helium escape from Earth into space.

So hydrogen, helium and many other things make up what's known as the Earth's atmosphere.

So I've told you that it happens at the rate of 400 pounds a minute for hydrogen and almost seven pounds for helium.

I mentioned helium on Earth and some oxygen and nitrogen, and from MAVEN we can also look at the oxygen being lost from Mars.

This happens after millions of years of heat and pressure have fused the star’s hydrogen into heavier elements like helium, carbon, and nitrogen— all the way to iron.

That way, we don't use fossil fuels or helium or hydrogen; we don't use solar panels or batteries or motors.

We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.

Helium's a gas; there're a lot of reasons why helium's good, it's a tiny molecule, it's inert, it doesn't give you narcosis.

But if we want to go deeper, of course, we need another gas supply, and helium is what we really need to go deep.

For dangerous environments or harsh, extreme places where it's hard to get people or equipment, they can assemble in the airspace, and as the helium dies, they then come back to the ground, and you're left with a big space frame structure.

While hydrogen and helium were made during the first two minutes of the big bang, the origin of heavy elements, such as the iron in your blood, the oxygen we're breathing, the silicone in your computers, lies in the life cycle of stars.

So without stellar death there would be no oxygen or other elements heavier than hydrogen and helium, and therefore, there would be no life.

Now, stars like our sun, which are relatively small, burn hydrogen into helium, but heavier stars of about eight times the mass of the sun continue this burning cycle even after they exhausted their helium in their cores.

It's that shape because the helium has to expand.

In the middle of stars, you're joining hydrogen together to make helium and then helium together to make carbon, to make oxygen, all the things that you're made of are made in the middle of stars.

For a moment they become helium 5, because they've got five particles inside them.

Deuterium and tritium goes together makes helium 5. Helium splits out, and a neutron comes out and lots of energy comes out.

That reaction at the bottom, that's lithium 6, plus a neutron, will give you more helium, plus tritium.

This is a high-altitude helium balloon.

Now, the reason we were able to come up with this is two key ideas: One is that this is similar to a cryogenic Dewar, something you'd keep liquid nitrogen or liquid helium in.

And the element helium was discovered just by staring at the light from the Sun because some of those black lines were found that corresponded to no known element.

And that's why helium's called helium.

It's hard to tell what's worse: Kathy Ireland's acting skills, or her ultra-high-pitched voice; the one that sounds like a screeching mouse on helium scratching its tiny little claws down a blackboard.

I'm still equally as impressed today with the musical numbers, each one a standout song with wonderfully dramatic lyrics in the epic tradition of 80's pop (think Pat Benetar on helium, only catchier).

What are the odds of a "Mermaid" helium balloon traveling from Yuba City, Ca.(on Nov 8th,1993) and landing 4 Days later,(on Nov. 12) in MERMAID, Prince Edward Island, Canada.(Approx.
