Matter disappears, or more precisely, it is converted into energy. Some problems are still being studied, and given the level of your junior high school students, to give you an example, the return capsule of the aviation encounters strong atmospheric friction, and some metals are converted into light and heat, and the total mass is reduced. You can do some chemical reaction tests in the school's precision closed electronic scale (such as combustion, which is a little more violent), anyway, whether it is gaseous, liquid, or solid, it is in it, and the mass can be weighed, and the quality will be known whether the quality has changed.
In addition, some of the food ingested will be converted into energy through decomposition, and transmitted from mitochondria and body fluids to the muscles of the whole body, which is also a kind of "disappearance" of energy, which agrees with the view of the upstairs. Also, fire cannot be simply understood as matter, it is a photothermal phenomenon, a state, not a gaseous state.

Fundamental theorems in physics: the law of conservation of mass, the law of conservation of energy. Matter is just circulating, constantly permuting and combining. And the energy that they (the earth's substances) are constantly circulating originally comes from the heat of the sun, and there is also part of the earth's geothermal heat.
That is to say, the driving force behind the change of matter on the earth basically comes from the sun, and the sun transmits its ability to us through the radiation of light. Light is a type of wave, with wave-particle duality, the essence of light is photons, defined as a matter of zero mass, with the ability to travel at the speed of light.
Fire is also light, and matter emits energy in the form of light, with heat (energy), and when it radiates out through the form of photons, so you can feel warmth. During a chemical reaction, fire provides energy to the atoms of each molecule to combine or decompose each other to achieve a reaction.
A junior high school student who is very studious and curious! Keep your curiosity alive, society should cultivate more such students.

Matter will disappear! When a substance is eaten, it will be broken down by cells, and the cells will be converted into heat!!
-
According to Einstein's mass-energy equation, the mass of matter can be converted into extremely high energy. This is an ordinary mass-energy conversion.
On the other hand, when positive matter collides with antimatter, both matter are annihilated. At the same time, gamma rays are excited.
From this it can be concluded that matter can be transformed into energy.
-
Fire is not a substance, it is a state in which combustibles release energy.
Light is a substance that has photons.
-
Broadly speaking, it is conserved.
-
From a philosophical point of view: matter disappears and it does not disappear. It may not be visible, but it is simply transformed into another substance; Or maybe it will disappear, and people will die and not be able to come back to life.
According to Einstein's theory of relativity, the disappearance of matter out of thin air will lead to a stable imbalance in space, which will lead to the instability of the three-dimensional world.
The law of conservation of matter means that matter does not disappear and will not be produced, but can only be transformed into another substance by one substance. The law of conservation of matter says that matter does not come into thin air, but only transforms from one form to another.

Summary. Substances that disappear quickly can refer to a variety of substances, depending on the context. Here are some possible explanations:
Chemically, a fast-disappearing substance may refer to a volatile or easily decomposing substance, such as volatile organic compounds. In physics, fast-disappearing matter may refer to particles that have a short lifetime or are unstable, such as neutrinos or antimatter. In everyday life, fast-disappearing substances may refer to items that are quickly used up or consumed, such as fast-disappearing food or cosmetics.

In physics, fast-disappearing matter may refer to short-lived or unstable particles, such as neutrinos or antimatter. In everyday life, a fast-disappearing substance may refer to an item that is quickly used up or consumed, such as a fast-disappearing food Kiriyama or cosmetics. Therefore, to be accurate about this question, more specific contextual information is needed.

Matter will of course disappear and can be converted into energy to gradually dissipate. The mass loss after coal combustion is due to the conversion of a large amount of substances into gases during the combustion reaction, and if it is in a closed container, the mass of the entire system remains unchanged after the coal is burned.
Coal combustion is a chemical change, and the chemical change only involves the change of the form of the substance, not the change of the properties of the substance. Coal is formed by ancient plants that are buried through complex physical and chemical reactions, and the coal seam contains non-combustible coal gangue.
and combustible coal, coal is organic matter, the main component elements are carbon, hydrogen, oxygen, nitrogen, sulfur, etc., organic matter can be fully burned at the appropriate temperature and oxygen concentration, and the product is carbon dioxide.
Water, nitrogen dioxide.
Sulfur dioxide, etc., and many organic and inorganic substances are dispersed with the flue gas, which is a chemical change, and the destruction and reconstruction of the intellectual composition in the whole process does not involve the change of element types, and the energy released is stored in the carbon skeleton of organic matter.
This is also the role of biological oxidation, and the energy stored in the conjugated bonds, etc., can be transferred to ATP for various life processes of living organisms. The significant reduction in weight after no combustion is due to the fact that more of the components are converted into gases and dissipated in nature, and if the reaction is carried out in a closed container, the total mass after the reaction remains unchanged.
Involving changes in the mass of matter are nuclear fission and nuclear fusion.
In that physical process, during nuclear fission, the element loses neutrons and becomes mass fraction.
Lower isotope phoneous tartarin.
or other elements, the process involves a slight change in mass; Nuclear fusion is a physical process that occurs in a high-temperature and high-pressure environment, due to the thermal shock movement of elemental nuclei at a very high speed at high temperatures, they will collide with each other, and with the assistance of pressure, the electrons will overcome the Coulomb force and be pressed into protons to form new elemental nuclei, which is also accompanied by mass loss.
Both processes involve the transformation of the mass of matter into energy. In the early evolution of the universe, there was also the conversion of energy into matter, first forming some basic particles at high temperatures, and then combining, and the easiest element to be formed by matter at high temperatures is hydrogen, because its structure is the simplest.
Matter will disappear, the law of conservation of matter.
It is applicable under the conditions of chemical reactions, while in the universe it may only be said that energy is conserved.
Matter can be converted into energy, and energy can also be converted into matter. From this point of view, matter will of course disappear.
-
Yes. Because matter is conserved and can only be transformed from one form to another, but does not disappear, it is true.
-
Matter will only be transformed, not destroyed, and will disappear out of thin air. According to the law of energy conversion and conservation, matter can be converted into energy and gradually transformed into other imitation matter. For example, hydrogen will release a large amount of energy after combustion, and then the hydrogen will disappear and form water.
-
Matter certainly does not disappear, and some substances will exist in other forms, or in other states. Matter, as the only characteristic of the world, refines the commonality of all things in the universe and refers to objective reality, which will not disappear.
-
Yes, because I feel like a woman's words are always materialistic.

According to the big ** theory, the universe in the big ** positive and anti-electron, positive and antiquark and other elementary particles are produced from energy in pairs, because the positive and anti-particles will be drowned when they meet and become energy, then, there should be only energy in the universe, and there will be no constituent stars, planets, cosmic dust, interstellar gas and other substances.
Prior to 1956, it was believed that elementary particles obeyed charge (C), mirror (P), and time (T) symmetry, as well as joint symmetry of CP and CPT.
In 1956, Lee Tsung-dao and Yang Zhen-ning discovered that the weak nuclear force that restricts the decay of matter will cause differences in the mirror image of particles, that is, this symmetry is not conserved, which is called "cosmic non-conservation". That same year, Wu Chien-shiung confirmed this phenomenon.
In 1964, Cronin and Fitz discovered that particle decay does not obey even the joint symmetry of CP by studying the decay of K-mesons.
In 1967, Sakharov deduced that at high energies, there is a slight difference in the decay rates of positive and anti-particles due to the non-conservation of CP joint symmetry of elementary particles, making positive particles slightly more than negative particles.
From this, people deduce that in the universe, for every 1 billion antiparticles produced, there will be 1 billion and 1 positive particles, and there will be one more positive particle than the antiparticle. Therefore, after every 1 billion positive and negative particles are annihilated, there will be one positive particle left, which constitutes the matter in the universe today.
Then, due to the continuous evolution of the recombination, the current form was formed. And it's not constantly evolving.

Religiously speaking, it was created by God, but this explanation is not enough to satisfy us; At present, Marxist philosophy believes that the fundamental unity of the world lies in its materiality, and that matter is something that really exists. As for why there is matter, this is not a question that can be thought of, but a question of continuous practice, and only through practice and continuous summarization and sublimation can we continue to understand the world, so that it is possible to have a solution to the problems that are difficult to solve now.
-
To determine why something exists, we first need to know our definition and understanding of it.
In a narrow sense, matter is regarded as objective things such as physical objects and fields that constitute all things in the universe; It is a form of aggregation of energy. Broadly speaking, we think of matter as being, and what exists is matter.
It is difficult to explain why matter exists from a narrow perspective, but we can understand that if there is no matter in a world, then there must be no living beings capable of perceiving the existence of this world, and we cannot ask this question. Although the problem exists objectively, it is no longer necessary.
And in a broad sense, the question of why something exists can make one fall into the endless whirlpool of philosophy, simply saying that what exists is existence, and what exists already exists.
-
The materialist view is that the world is made of matter and is atheistic, but idealism is not necessarily, and it depends on people's beliefs.
-
The universe is great.
-
That's how you have the opportunity to ask the question and post it up.
Even if I didn't say it, there is no Amitabha Buddha in the south!
-
Don't be disgusted with women's materialism, because they see that there are too many women who are not materialistic and are still abandoned and hurt! If you are true, she will be true, and if you are false, she will immediately turn around.
-
This is simply a fart, what exists is existence, what fart, I don't know the best.
-
There are things in the world that we can feel and call things, they have weight, they have shapes, they are called qualities. So there was matter.

From the perspective of energy, cremation energy is also conserved, just like burning firewood, where do you think the firewood goes after burning? Turning into ash and turning into gas are both a type of substance. Matter itself is conserved.
From your words, it is scientifically possible to replicate a person exactly the same person at that moment, including every cell of his person, every brain current, if technically possible. But once it is copied, from that point in time, the mind, matter, and spirit are all different.
The carrier of spirit and thought must be matter, but what is spirit and thought itself, this is philosophy, and there is no conclusive conclusion in science, which is why many scientists have studied and later become theologians.
It's just a personal understanding, so let's use it as a reference.
-
Conservation of matter.
When a person dies, it's a pile of organic matter.
It is then broken down by microorganisms and turned into carbohydrates.
Youth, materialism does not recognize spirit as material.
Matter can certainly restructure a person.
However, people have relatively high requirements for materials, so it is basically difficult to reorganize people to realize that vegetative people have no spirit and mind, but they are still individuals.
-
After death, man still returns to nature and becomes a material in nature, preparing the material basis for new life.
Also, in an infinite amount of time, there will come a time when there will be exactly the same recombination, this is not true, the atoms will decay, the molecules that make up your atoms protons and quarks also have a certain lifespan, they will not reorganize anymore.
I tend to die as if people are waiting for death, materialists, idealists may have gentler words that can make you more acceptable.
I'm sorry, dead is dead, live well.
Love will definitely disappear, because when the contradiction between two people cannot be resolved well, the gap between two people will become bigger and bigger, and love will become less and less.
The sun doesn't go away. But it will exit the main sequence after its own nuclear energy burns out, become a red giant, then shrink due to its gravitational pull and throw the outer material into space, and finally, the sun's inner core will shrink into a very dense, faint and cold star, a white dwarf. >>>More

It's always sung in the song, love always appears very simply, and the end is unreasonable, it's a pity to think about it. However, he also said that everything has a cause and must have an effect, and the cycle of cause and effect may be because of self-deception. Therefore, there is always a certain reason for the disappearance of love, and below, let's take a look at why the love of the 12 zodiac signs disappeared. >>>More
