Is there some kind of relationship between light and fire? 15

Fire is a phenomenon in which oxidized substances are violently combined with oxidized substances to emit light and heat. In fact, the fire you usually see is the light scattered by flammable materials when they burn (combined with oxidation). This light is produced by the scattering of photons in space during the electron transfer of oxidation reactions.

Photons are one of the several elementary particles that make up matter and have mass, so light also has weight. The book you read is wrong.

Where there is fire, there must be light, but where there is light, there is not necessarily fire.

Both light and fire can be said to be phenomena.

And all have energy.

Both light and fire are a phenomenon.

But what happens to some fires that don't have light?

Difference Between Light and Fire:

1. The definition is different.

Light is a physical term whose essence is a stream of photons in a specific frequency band.

The original meaning of fire refers to the light flame produced when the object is burned, and it is later extended to the meaning of ** or shooting, anger, hot and hot qi in traditional Chinese medicine, heat, red, etc.

2. The form is different.

A light source emits light because the electrons in the light source gain extra energy.

Fire is an intense oxidation reaction that takes place during the combustion of matter, and its energy is released in the form of light and heat, in addition to producing a large number of products.

3. The conditions under which it occurs are different.

Light refers to the fact that the electrons in the light source gain extra energy, causing the original electrons to jump and return to their original orbits, and the energy is released in the form of waves.

According to the law of conservation of mass, fire does not make the atoms of the combustible object disappear, but only transforms the molecular form of the combustible object through chemical reaction.

4. The form is different.

Light has wave-particle duality, which is both a wave and a particle, and its basic form is a light particle, which carries energy.

The visible part of fire, called flame, can take on different shapes as particles vibrate, and can take the form of plasma (fourth state, similar to gas) when the temperature is high enough. Depending on the substance burned and the purity, the color and brightness of the flame will vary.

The fire is usually called a flame, that is, the combustion of flammable gases (wood is heated to produce flammable gases, there is a flame, there is no flame when charcoal is burned, and a large amount of charcoal is burned with a faint flame that is caused by the combustion of carbon monoxide produced by carbon and oxygen), combustion produces high temperature so it glows and light is electromagnetic waves, including visible and invisible.

In Luffy's words: fire can roast meat, light cannot. In the words of ordinary people, fire can emit light, but it depends on a magnifying glass (scientific name convex lens) to make fire.

Fire includes light Light does not include fire.

1.The "Divine Six" can be sent to the sky.

2.Can bake cooked food.

3.It is possible to warm up in the field.

4.Can defend themselves.

The first is the need for human survival, slash-and-burn, and Hu Ming is the most primitive use of fire The second is the need of human life, making fire and cooking, is the most widespread use of fire and the need for human production

Fire luminescence occurs because the molecules in the flame are in an excited state.

Ignition means that a chemical reaction occurs.

The electronic state of the molecule of the reaction product.

Not necessarily in the ground state.

Some product molecules are in an excited state.

The so-called excited state is the electron in the molecule.

It is not in the most stable state of the shirt.

Electrons in the excited state of the molecule.

Jumps will occur.

Transition from a high-energy state back to a low-energy state.

The energy in it.

It was released in the form of light.

The emitted light is usually the same kind of flame related to the energy difference of the above-mentioned transition process.

Analyze the spectrum it emits.

It should all be the same.

There used to be always asking.

What kind of substance is fire?

There is always someone who is plasma.

Not entirely.

Low temperature flames.

It mostly exists in the form of molecules in an excited state.

In other words, most of the flames seen in the daily life of the closed hall are gases.

1: My personal understanding is that "firelight" refers to "ideal stool", "hope" and other beautiful and distant things "River of Life" refers to the road that people have traveled in their lives, and the things they have experienced "Harder paddling" refers to the author's eagerness to find the fire in his (her) life, alluding to his yearning for a beautiful and clear new sparrow and life

2: After reading this article, I suddenly felt that my dream was far away from me, not as close as I imagined, and it took a lot of hardship to achieve my dream, so if you want to succeed, you must start from now, don't imagine success so simple What I want to say most is to tell many people who think they are about to succeed, don't relax, because maybe success is still far from you What I want to do is, of course, "work harder" and look forward to early success
