What substance is fire made of?

To exist is to matter. It does not matter whether it exists objectively or subjectively, as long as it exists, it is matter.

Matter is divided into "matter" and "quality". "Things" are entities, and "qualitative" entities are the connections between them.

At present, the smallest concept of "matter" is electrons, protons, and neutrons, and entities are all of them. "Quality" is the connection between them, including "field", "wave", "force" and so on.

"Fire" is also a connection between entities, which belongs to "quality".

Gases, liquids, and solids are all forms of solidity, and cannot be used to measure "quality".

It is important to note that the plasma state is also an entity and is also made up of electrons, protons, and neutrons.

Plasma. It's just electrons and metal ions.

Take a look at Big Tech Science Mystery 99 issue of someone mentioning this problem.

Editors have. Refer to it for yourself.

Plasma, the fourth state we call is made up of atoms like matter, but the atoms are in violent motion.

Fire is a form of energy reaction, not matter.

is a phenomenon.

Chemical reactions, a phenomenon and a process.

It can be a variety of substances reacting, not necessarily just two.

Fire is made up of a large amount of heat released.

Fire is the light and heat released by violent chemical reactions.

Fire is an energy substance. 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. Slow oxidation reactions, such as rusting or digestion, are not included in the definition above.

Introduction

When flammable substances (fuels) are mixed with sufficient oxidants (such as oxygen, substances with high oxygen content or other oxidants that do not contain oxygen), and when exposed to a heat source or a temperature higher than the flash point of the fuel and oxidant mixture, it will burn, and can maintain a rapid oxidation reaction to form a chain reaction, which is generally called fuel, oxidant, heat and chain reaction as combustion tetrahedron.

If there is no above elements, or the proportion is not right, it can not be combusted, for example, flammable liquids will only be burned within a certain proportion of liquid and oxygen, and some mixtures of fuels and oxidants need catalysts to burn, catalysts are substances whose quality remains unchanged before and after the reaction, but when there is a catalyst, the fuel and oxidant can be burned more stably. After the fire is ignited, as long as the fuel can maintain its temperature through the release of heat energy, a chain reaction will occur, and if the fuel and oxidizer are continuous, the fire may spread.

Fire is composed of various high-temperature gases, because these gases obtain a lot of energy in chemical reactions, so they release energy to the outside world in the form of luminescence and heat, this is what we see as fire, and we can also understand fire as a combination of light and heat.

Fire is the light and heat produced by the combustion of matter, and is a type of energy. There must be combustibles, ignition points, and oxidants to make a fire. Without any of the three, no fire can be made.

Fire is a chemical process in which the form of matter changes, it is not a substance. Simply put, fire is the energy produced when matter is burned, including light and heat. The conditions for the production of fire: combustibles, ignition points, and oxidants are indispensable.

Flame is visible light formed after combustible materials are mixed with air and burned. The fire is composed of a flame core, an inner flame, and an outer flame, and different parts show different colors due to different contact with the air.

Fire is not a substance. Fire is generally a form of energy released by a chemical reaction between substances. Just like **, it is a form, not a substance, and there is no mass, but the substance contained in this form has a mass volume.

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

Matter is the physical objects and fields that make up all objects in the universe. All entities in the world are matter, and the human body itself is also matter. In addition to these physical objects, light, electromagnetic fields, etc., are also substances, and they are substances that appear in the form of fields.

Although there are many types of matter, they have their own characteristics, that is, they can be observed or predicted by theories, and they have mass and energy. Having different chemical formulas is different substances, and having the same chemical formula but having different structures is also different substances.

Fire is made up of matter in the plasma state;

In 1879, the British physicist Crookes determined that plasma was the fourth state of matter;

Explanation of plasma: electrons leave the nucleus, this process is called "ionization", at this time, the substance becomes composed of positively charged nuclei and negatively charged electrons, a uniform "paste", people call it ionic slurry, the total amount of positive and negative charges in these ionic slurries is equal, so the buried beam is also called plasma excitation;

The fire that is commonly seen is the photon emitted when the ionized electron returns from the excited state to the ground state, and the photons of different energies have different energy colors, so the color of the fire liquid circle is also different.

Fire (ignition) is a special form of matter.

Fire is a strong oxidation reaction carried out during the combustion of an object, and the light and heat emitted by it are a phenomenon of energy release.

The visible part of fire, called flame, can take on different shapes as particles vibrate, and can appear as a plasma (fourth state, similar to gas) when the temperature is high enough. Another theory is that the incandescent phenomenon is produced by the reaction of the substance due to the high temperature, such as the carbon dioxide produced after the combustion of carbon emits light due to the high temperature.

Fire is a phenomenon in which certain substances are combined or decomposed to release energy; In addition to light particles and derived particles, this energy is a secondary generation of matter that carries different thermal energy. In addition to the strong oxidation reaction, fire also has other physical phenomena presented by strong chemical reactions. At the same time, oxygen is also a fuel for fire.
