How is a flame formed? How the Flaming Mountains were formed

Flames are produced by the combustion of flammable gases or vapors. Solid combustion is flameless.

Usually when H2, Co, and CH4 are burned, there is a flame because this is the gas combusting.

Didn't you say earlier that there is no flame in solid combustion? But why do you see flames when the sulfur and magnesium belts burn? This is because the melting point of these substances is relatively low, and when the heating begins, or the heat released by the reaction causes the solids to melt and produce S or Mg vapor, these vapors burn to produce flames.

Why does iron burn but there is no flame? This is because the melting point of iron is very high, and the heat released by heating or reaction is not enough to melt the iron, and the vapor of iron is not produced, so there is no flame for the combustion of iron.

The flame is produced by the burning of a piece of charcoal because the charcoal contains wood tar, which turns into steam when heated, and these steam are burned again to produce a flame.

If a pile of charcoal is burned, the cause of the flame is not only the reason that the charcoal contains wood tar, but also because of the flammable gas CO, CO is then burned to produce a flame:

c+O2==ignition==CO2

C+CO2==High temperature==2Co

2CO+O2==Ignition==2CO2 (Produces flame).

Fire is the process of releasing energy, and the formation of fire is like the food you eat into organic energy that can be used, giving you the strength to move. It can also be said that fire is a substance, and conceptually speaking, fire is a large piece of plasma formed after the electrons of a substance lose photons.

In addition, there is a flame in iron combustion, but the oxygen content in the air is not enough, so the phenomenon we see is only that the iron is red and hot, but if it is in pure oxygen, you can see that the iron combustion is sparkling, and after combustion, there is a black solid generated, and when that thing is ferric tetroxide (let the teacher help, it is dangerous to do it yourself, when burning the iron wire in the gas collection cylinder full of pure oxygen, the bottom of the gas collection cylinder should be spread with 1 4 volumes of sand in the bottle to prevent bursting), and burning in the air will also generate a black solid (attached to the surface of the wire) , that thing is ferric oxide.

In addition, carbon burns more violently in pure oxygen.

This knowledge will be learned in the third year of junior high chemistry.

Flaming MountainThe formation is formed by the accumulation of sand and soil about 100 million years ago. At that time, the climate was unusually hot, and the iron element in the sand, gravel and soil was piled up.

After high-temperature oxidation, a large amount of red iron oxide is formed.

Later, with the movement of the earth's crust, it rose into a mountain, and it rose in the deep concave Turpan Basin, forming a flaming red background of the Flame Mountain.

Flame Mountain, known as Chishi Mountain in ancient times, is located on the northern edge of the Turpan Basin, the northern route of the ancient Silk Road. It runs east-west. Flaming Mountain, Uyghur.

It is called "Kiziltag", which means "red mountain", and the Tang people used to call it "volcano" because of its heat. The mountain is more than 100 kilometers long, the widest point is 10 kilometers, the altitude is about 500 meters, and the main peak is meters above sea level. Flame Mountain, Tong Mountain, bald mountains, no grass, birds hidden.

Whenever in the middle of summer, the red sun is in the sky, the russet mountain is under the scorching sun, the sandstone is scorching and flashing, and the blazing air flow rolls up, just like the flames are blazing, and the tongue of fire is touching the sky, so it is also called the flame mountain.

Huoshan is the hottest place in China, with the highest temperature in summer, the highest surface temperature as high as 89, and hard-boiled eggs can be baked in the sand nest. Turpan has a typical continental arid desert climate. Although the average annual temperature is only.

Flames are produced by the combustion of flammable gases or vapors. (When burning, there will be a transition and transfer of electrons, and a part of the energy will be released in the form of visible light.) ）

For example, a piece of charcoal burns quietly to produce a flame because the charcoal contains wood tar, and the wood tar turns into steam when heated, and these steam is burned again to produce a flame.

If a pile of charcoal is burned, the cause of the flame is not only the reason that the charcoal contains wood tar, but also because of the flammable gas CO, CO is then burned to produce a flame:Chemical formula: C+O2==Ignition==CO2, C+CO2== High Temperature==2Co, 2CO+O2==Ignition==2CO2 (Flame).

There is no flame in solid combustion, so why do sulfur and magnesium burn but also see flames?

This is because the melting point of these substances is relatively low, and when the heating is started, or the heat released by the reaction causes the solids to melt and produce steam that bends S or Mg, and these vapors burn to produce flames.

Flame is a state or phenomenon, is the phenomenon of the release of light and heat when the oxidation reaction between combustibles and combustibles occurs, and the combustible liquid or solid must first become a gas before it can be burned to generate a flame, mainly because the combustible gas is oxidized by the air or simple oxygen and glows and heats.

1. The inner layer, with blue, is incomplete due to insufficient oxygen supply, the lowest temperature warning, and has a reducing effect, which is called the internal flame or reducing flame;

2. The middle layer is bright and the temperature is higher than that of the inner layer;

3. The outer layer, colorless, due to sufficient oxygen supply, complete combustion, the highest temperature, oxidation, called the outer flame or oxidation flame, or divided into flame core, inner flame and outer flame, the flame temperature state discrimination increases from the inside to the outside;

4. The center of the flame, the dark part of the center, is composed of gases that can be burned but have not yet burned;

5. The inner flame, the brightest part that surrounds the center of the flame, is the part of the gas that is not completely burned, contains carbon particles, is heated to emit strong light, and has a reducing effect, also known as the reducing flame;

6. The outer flame, the outermost almost dull part, is the part of the gas that is completely combusted, containing excessive and strong hot air, with oxidation, also known as oxidation flame, the flame is not all high-temperature plasma, and flames can also be produced at low temperatures. The sail is missing.
