Heat turns water into steam.

You'll understand how Mama felt. Why so paternal suddenly?

Water expands with heat.

We drain it and she'll fry.

Heat changes ice into water.

Heat turns water into steam.

And do that, and spread the word.

IF, as scientists suspect, Europa has volcanic activity.

Let us be heard from red core to black sky.

And then once we've added this much heat, now we're just heating up the steam.

Heat turns ice into water.

Both of these fuels can be converted to synthetic crude oil.

Water changes into vapor when it is heated.

We didn't have any idea about these things, which we call chimneys.

Myrtle there aren't merpeople in the Black Lake, are there?

Water will boil if heated enough.

O.K.? Radical, not subtle.

But 10 miles down the ridge... pshhh!

It's not this

And that we have!

As we did some of our subsequent expeditions,

So you can generate electricity from the gas turbine, and you've got to cool the gas, and every thermodynamic cycle has to reject waste heat.

It's actually a light sensing organ.

Is there another way?

During hot weather, be sure to drink lots of water.

Here's where Bill's cameras really do shine.

In Japan solar heat is used more for solar water heaters than for electricity generation.

And there's a whole new hydrothermal vent community that has been formed.

This is the target site, the world's deepest hydrothermal spring at Cenote Zacaton in northern Mexico.

And I remember looking into the ice, and there were big chunks of white ice in there, and the water was completely black.

As the bath is too hot, I will run some cold water into it.

Ilya, darling... You see how simple it is...

Let me discuss the second quiz here, in which we're given two scan lines again a left and a right scan line.

The pH of 11, and yet it had chemosynthetic bacteria living in it and at this extreme environment.

In the experimental EGS system, two shafts would be drilled 6 miles deep.

We have problems.

Boots, black. Belt, black.

You're always

And what scientists didn't predict is that, as this ice melts, these big pockets of black water are forming and they're grabbing the sun's energy and accelerating the melting process.

What you're seeing when you put it through a prism is that you heat hydrogen up and it doesn't just glow

Red phosphorus in the presence of moisture and accelerated by heat yields phosphorus hydride.

Blacky. Blacky, hang in there.

Not like hot water made cold, or cold water turned hot, but water boiled off and becoming steam.

If you start with water and you make it colder and colder and colder to zero degrees, you're essentially taking heat out of the water.

I've been dipped in.
