Helium

Helium is a gas.

Product Helium gas

Helium is a gas.

The Lambda point is the temperature below which normal fluid helium (helium I) transitions to superfluid helium II (approximately 2.17 K at 1 atmosphere).

And that's why helium's called helium.

Deuterium and tritium goes together makes helium 5.

Helium has 2 protons. Carbon has 6 protons.

And so an example, this is helium gas. Helium gas is made up of only one atom.

So if you had let's say you had liquid helium, which you'd have to get very cold to get.

Helium splits out, and a neutron comes out and lots of energy comes out.

And you might be thinking, I wonder why that is?

So, that's that process there. Deuterium and tritium goes together makes helium 5.

Helium, neon, argon, krypton, xenon and radon are noble gases.

The two main constituents of the Jovian atmosphere are molecular hydrogen () and helium.

Now 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.

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.

In normal A F G stars He is neutral in the stellar photosphere.

And what you find is that we have a lot of hydrogen and helium.

In the core of one star hydrogen fused to form helium... later, beryilium.

In the 1950s, people were trying to figure out how superfluid helium worked.

After about a few minutes, there was hydrogen and helium in the universe. That's all.

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

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

We need helium, and the helium is what we really need to go deep.

Helium 3 very rare on the surface of the Earth, very common in space.

And that's what we use to inject, as we start to do our deep dives.

That's what we use to inject, as we start to do our deep dives.

So each row is a period and then for the porposes of figuring out the electron configuration we did this in the last video we want to put helium

Due to higher atomic mass, any helium in the envelope will have sunk beneath the hydrogen layer.

Helium was used to pressurize the fuel tanks but should not have been in the combustion chamber.

launched into space on duty violent green hydrogen and Helium raw material universe

And the cool thing about it is when we convert hydrogen to helium we actually lose a little bit of mass.

Most extraterrestrial helium is found in a plasma state, with properties quite different from those of atomic helium.

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

One is that this is similar to a cryogenic Dewar, something you'd keep liquid nitrogen or liquid helium in.

The vast majority of helium was formed by Big Bang nucleosynthesis one to three minutes after the Big Bang.

He also isolated helium which had been observed in the spectrum of the sun but had not been found on earth.

I've talked a lot about the philosophy and all of that, but how do I know that this is helium?

Well the sun, is actually, gets it's energy from hydrogen fusing into something called helium.

Composition The composition of the Uranian atmosphere is different from that of Uranus as a whole, consisting mainly of molecular hydrogen and helium.

It uses gas, so supercritical CO2 or helium, and that goes into a turbine, and this is called the Brayton cycle.
