A hot gas is producing emission lines only, no continuum.

Thermal airships use a heated lifting gas, usually air, in a fashion similar to hot air balloons.

Compressed Natural Gas (CNG), largely methane, is another gas used as fuel, but it cannot be liquefied by compression at normal temperatures, as these are well above its critical temperature.

Some puzzles involve using the environment to kill an enemy, like turning on a steam valve to spray hot steam at their enemies.

In general, this is the case where the Mach number in part or all of the flow exceeds 0.3.

The main valve is turned off.

And if you place a cool gas in front of a hot source, you will see certain patterns which we call absorption lines.

Many of these new trombone valve designs have enjoyed great success on the market, but the standard rotary valve remains the most common for trombone valve attachments.

As stars are born within a GMC, the most massive will reach temperatures hot enough to ionise the surrounding gas.

This is actually a heart valve, which we engineered.

And this is how you make a valve.

In practice, the language barrier impairs this safety valve.

Engineers ordered the valve closed and the countdown continued.

And once it's in the right spot, they remove the outer shell, and the heart valve, well, it gets this shape and at that moment it starts beating, instantly.

Note that this pressure increase is more than a simple 10 1 compression ratio would indicate this is because the gas is not only compressed, but the work done to compress the gas has also heated the gas and the hotter gas will have a greater pressure even if the volume had not changed.

A plasma is sometimes referred to as being hot if it is nearly fully ionized, or cold if only a small fraction (for example 1 ) of the gas molecules are ionized, but other definitions of the terms hot plasma and cold plasma are common.

It was hot. It wasn't hot enough.

And the way you engineer this heart valve is the same strategy.

The number of neurons in the cerebellum is related to the number of neurons in the neocortex.

The presence of methane, a powerful greenhouse gas, in Pluto's atmosphere creates a temperature inversion, with average temperatures 36 K warmer 10 km above the surface.

Does the color of the valve matter? What matters here?

He was born with an incompletely formed heart valve.

It's hot.

This is actually a heart valve that we've engineered, and you can see here, we have the structure of the heart valve and we've seeded that with cells, and then we exercise it.

Now that's a left ventricle pushing blood up through the aortic valve you can see two of the leaflets of the aortic valve working there up into the ascending aorta.

I like coffee hot.

It was hot last night.

I'd like to have some hot chocolate.

I'd like to drink something hot.

I'd like to drink something hot.

Of this, is land and water.

The first valve lowers the instrument's pitch by a whole step (2 semitones), the second valve by a half step (1 semitone), and the third valve by one and a half steps (3 semitones).

At the same time, gas lights using natural gas or coal gas were coming into wide use.

Gas spring a volume of gas which is compressed.

Rotary valve engines can be tailored to deliver power over a wider speed range or higher power over a narrower speed range than either piston port or reed valve engine.

Warm air has a lower density than cool air, so warm air rises within cooler air, similar to hot air balloons.

The household microwave oven uses a magnetron tube to efficiently generate hundreds of watts of microwave power.

Environmental effects Effect of natural gas release Natural gas is mainly composed of methane.

There's a funny kind of hot plate here, with vent water coming out of it.

It's pretty hot.

Veggie dog.

It's hot today.

It's too hot.

It was very hot.

It is too hot.
