And there's dehydration.

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

Cycle cryofans. Colonial One, this is Picon 36.

Cold! Those are my eyes! Freezing!

And I remember....

A greenhouse effect. Everything is burning up.

Conventional wisdom says set it low, at or near room temperature, and then install a control system to keep it there.

The survivors came in one by one.

I think I've got hypothermia.

So this is a satellite photograph based on temperatures red being warm, blue being cold and we found there's a tremendous difference between the warm water samples and the cold water samples, in terms of abundant species.

So what you're looking at here is a heat image of the system, and what you can see here emerging from the poo is a cool dung ball.

like the Amazon rainforest you're hearing behind me.

Low temperatures turn water into ice.

Today's minimum temperature was 3 C.

Today's low was 3 degrees Celsius.

It isn't climbing.

We learned it was warmer at lower elevations.

How did he get hypothermia?

It's not going to feel this good all the way across.

The temperature's dropping too rapidly.

Because the pressure is low The water boils at only 85 C

And the reason the efficiencies are so low is these reactors operate at pretty low temperature.

There is less heat in the air at 3 than at 1 .

EB The outside can get almost as hot as the surface of the Sun.

Keep it at a lower temperature.

The cryogenic protection pod is designed to put you into a deep sleep for...

We try to keep our core temperature at 37 degrees by actually burning more oxygen.

It gets very expensive to do this research.

Our high will get to about 30 today, teens tonight.

I took my temperature, but it was normal.

It's about the same as yours and mine.

Now let's say at low temperatures I'm here and as I add heat my temperature will go up.

Where nothing cheers nor saddens, but a fire

I'll use magenta.

Unusually low temperatures account for the poor rice crop this year.

The water temperature's still low so you're not going to swim, are you?

Milk has to be kept at a relatively low temperature.

Here is the lower atmosphere.

So this is when I have very little heat and I'm increasing my heat.

Radiates heat more effectively in warmer climates.

On the top, now, that is a temperature record of a mouse who has gone through the dotted line, the temperatures.

Now, the same mouse is given 80 parts per million hydrogen sulfide in this solid graph, and look what happens to its temperature.

And this is temperature.

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