Metal contracts when cooled.

It has cooled off.

Hydrogen

Hydrogen

So hydrogen, this hydrogen, might have one.

So hydrogen has a covalent bond with another hydrogen.

My love for him has already cooled.

I cooled the patient's head with ice.

Again, the universe cooled and tiny electrons were captured into the nucleon's orbit. Due to gravity, knots of hydrogen gas began to coalesce into large knots... ...eventually forming galaxies.

Reminiscent of hydrogen sulfide.

It's between two isotopes of hydrogen, two kinds of hydrogen deuterium, which is heavy hydrogen, which you can get from seawater, and tritium which is super heavy hydrogen.

You have a hydrogen here that just has a 1s orbital. It has a hydrogen here, 1s orbital, hydrogen here, 1s orbital.

I cooled my heels for one hour outside his office.

The very nearness of the fire but cooled our ardor.

Water contains hydrogen and oxygen.

Oxygen and hydrogen make water.

The monkeys make hydrogen bombs

You have a hydrogen here.

Now, in a water cooled reactor, you have a system called a recombiner that will take the hydrogen gas and the oxygen gas that is always being created from the nuclear reaction and put them back together, because chemically they'd much rather be water than being hydrogen and oxygen.

Water consists of hydrogen and oxygen.

Water consists of hydrogen and oxygen.

Water consists of hydrogen and oxygen.

Water consists of hydrogen and oxygen.

The chemical symbol H expresses hydrogen.

You have some bonds to hydrogen.

This makes a Hydrogen economy unlikely.

80 parts per million hydrogen sulfide.

This hydrogen is kind of in the plane of the page, and then maybe that hydrogen is behind it, and then you have one hydrogen popping up.

A hydrogen just has one electron in the 1s orbital, so the hydrogen has a 1s orbital.

You have to build a water cooled reactor as a pressure vessel.

So it kind of cooled my test driving for a little while.

The atomic number for hydrogen is 1.

Hydrogen and oxygen combine to form water.

It's made of oxygen and of hydrogen.

So by definition, hydrogen has 1 proton.

So let me talk about hydrogen first.

low concentrations of both hydroxide and hydrogen.

lower state, which is the hydrogen iodide.

Hydrogen has one proton, helium, two protons,

So water cooled reactors have to run at over 70 atmospheres of pressure.

The universe cooled, allowing quarks to bind into groups of three, forming baryons.

Hydrogen does not exist as such in nature.

Water is made up of hydrogen and oxygen.

Water can be decomposed into oxygen and hydrogen.

The treaty bans atomic bombs and hydrogen bombs.
