Does burning on the surface of the sun consume oxygen?

The sun is not as simple as burning with oxygen! See the following explanation: The Sun is a hot gas planet that glows on its own.

The temperature on its surface is about 6,000 degrees Celsius, and the core temperature is as high as 15 million degrees Celsius. The radius of the Sun is about 696,000 kilometers, which is about 109 times the radius of the Earth. Its mass is tons, which is about 332,000 times that of the Earth.

The average density of the Sun is grams per cubic centimeter, which is about 1 4 of the density of the Earth. The average distance between the Sun and our Earth is about 100 million kilometers. The structure of the sun from the inside out is mainly divided into:

The center is the thermonuclear reaction zone, and beyond the core is the radiation layer, which is the troposphere, and beyond the troposphere is the solar atmosphere. According to the theory of nuclear physics, the center of the sun is a thermonuclear reaction zone. The central region of the Sun occupies 1 4 of the entire radius of the Sun and is more than half of the mass of the entire Sun.

This indicates that the density of matter in the central region of the Sun is very high. Up to 160 grams per cubic centimeter. Under the attraction of the sun's own strong gravity, the central region of the sun is in a state of high density, high temperature and high pressure.

It is the birthplace of the sun's immense energy. The energy generated in the central region of the Sun is mainly transmitted in the form of radiation. Beyond the central region of the sun is the radiant layer, which extends from the radius of the sun at the top of the thermonuclear center to the radius of the sun, where the temperature, density, and pressure decrease from the inside out.

In terms of volume, the radiant layer accounts for the vast majority of the total volume of the Sun. Through thermonuclear fusion, the sun emits light by burning large amounts of hydrogen concentrated at its core, consuming an average of 6 million tons of hydrogen per second. After another 5 billion years, the Sun will deplete its hydrogen reserves, and then the nuclear region will shrink and the nuclear reaction will expand to the outside, where its temperature can reach more than 100 million degrees, leading to helium fusion.

No, you don't. Because the interior of the sun is exothermic by fusion. Beg.

<> there is no oxygen on the sun, but why is it able to burn? In fact, it is not correct to say that the sun burns, because the normal combustion reaction will have three major elements: the ignition source, oxygen, and combustibles, and will also produce the residue of burning materials.

The phenomenon is not a combustion phenomenon, but a nuclear fusion and destruction of the forest transformation reaction.

So, what is called a nuclear fusion reaction? The sun's nuclear fusion reaction is to take four hydrogen atoms.

The process of fusion into a helium atom, 4 million nuclear matter is fused in the sun every second, and in the process the sun constantly releases energy, Einstein.

The intelligent equation.

To be able to explain it effectively, the energy produced by nuclear fusion is an ordinary chemical reaction.

20 million times the energy released, in other words, the energy released by the fusion of one kilogram of hydrogen nuclei into helium atoms is equivalent to the energy released by burning 4,000 tons of oil, or 6,000 tons of coal, which shows how much energy the sun brings to us, it is the light and heat generated by this physical reaction, not the combustion required by ordinary chemical reactions, it is worth mentioning that the sun has been nuclear fusion for 5 billion years, and the energy he brings us is enough to support the reproduction of all living organisms.

According to scientists' calculations, the central temperature of the sun is as high as 15 million degrees Celsius.

It is a collection of high temperature, high pressure, high density as one of the region, the energy released by the solar nuclear fusion reaches the surface of the sun when the temperature will be reduced to 6000 degrees Celsius, but this temperature is enough to melt all foreign objects, so, with the current detection of human beings can only reach the part outside the sun, but it is certain that the sun's light and heat are consumed at a rate of millions of tons per second, so his energy is not endless, according to scientists' estimates, Nearly half of the sun's energy spine has been consumed in these 5 billion years, and the other half can be maintained for about 5 billion years, when the nuclear reaction inside the sun expands from the inside out, the temperature of the sun's surface rises, the volume expands, and finally comes to an end.

There is no oxygen on the sun, because the sun produces a lot of heat, and it will burn with other things, so it can burn.

There is oxygen on the sun. This is because the sun has a certain amount of solar energy, and the sun also undergoes thermonuclear fusion reactions, so it burns.

Of course there is no oxygen. Because the inside of the sun there will be nuclear fission, nuclear fusion, there will be hydrogen atoms, so it will burn.

In our common sense, it seems that there must be oxygen for combustion, but there is no oxygen on the sun, but it still burns for billions of years. Then the following is byKnowledge of horoscopes

How can the sun burn without oxygen?

First of all, we must clarify two facts, first, oxygen is not a necessary condition for combustion, that is, Feng Chuan said, combustion can be achieved in the presence of oxygen, but if there is no oxygen, it can still be burned, for example, as we all know, magnesium strips are burned in the absence of oxygen, and hydrogen can also be burned in nitrogen, these chemical reactions can be combusted, but oxygen is not needed. Therefore, it can burn even in the absence of oxygen.

Second, although the sun can shine and heat, it is very similar to the combustion in our lives, but in fact, the sun is not burning, specifically, the special geographical environment of the sun, the silver field model, so that hydrogen is in the process of continuous nuclear fusion, producing helium at the same time, releasing a large amount of energy, and these abilities will be released in the form of light and heat. Although combustion is also the release of heat and light, there is a fundamental difference between the two. So, we can explain the above problem.

First of all, because combustion is not necessarily related to whether or not it is in an oxygen environment, the sun's luminescence and heat have nothing to do with oxygen. Therefore, the sun will not affect the sun's luminescence and heat in an oxygen-free environment, so even in the oxygen-free environment of the sky, the sun still shines normally, providing the light and energy we need to survive. Secondly, the reason for the energy released by the sun is nuclear fusion, and more figuratively, the hydrogen bomb was invented with such a theory.

Therefore, the principle of the sun is similar to that of the hydrogen bomb, which exhibits similar properties to combustion through physical changes. At the same time, a large amount of energy is released. Because of the sun's environment, the amount of hydrogen is unlimited, so even though the sun has existed for billions of years, it still maintains the same nuclear fusion process to provide the environment needed for the earth's body.

So without oxygen, the earth can still shine for billions of years, but this is not combustion, and it has nothing to do with oxygen.

Because the sun is rich in oxygen and nuclear fusion is taking place, it will continue to burn without oxygen.

The solar combustion we see is a process of thermonuclear fusion, not the combustion of oxygen, so the sun will continue to burn without oxygen.

Because the sun it is a new one, and it is a natural phenomenon, although there is no oxygen to come back and forth, only to burn. So, everything in our world is very magical.

For a long time, we didn't know much about the sun or even why it glowed. You know, you need oxygen to burn, but there is no oxygen in vacuum space, and this idea was overturned back at the end of the 19th century, when scientists analyzed the spectrum of the sun and found that the sun is mainly composed of hydrogen and helium, hydrogen makes up about three-quarters of the sun's mass, and the rest is almost all helium. The amount of oxygen in the Sun is only about about the mass of the Sun, which is not enough to support the Sun burning in a vacuum in space.

In the 20s of the 20th century, physicist Francis Aston made an interesting observation: the combined mass of four individual hydrogen nuclei is always slightly greater than the mass of one helium nucleus. When the hydrogen nuclei are fused into helium nuclei, they must be brought very close together so that the protons of the strong nuclear force (also called the strong nuclear force) can be tied together, but the protons are actually protons, and the protons are positively charged, so there is a repulsive force between the protons and the protons, and in this case, the protons must have a very high kinetic energy to overcome this repulsive force.

Mercury and Venus warm everything in the world and their surfaces are very hot near the Sun, while Uranus and Neptune are far away from the Sun and their surfaces are very cold. Although the sun is like one"Fireballs", but it's completely different from what we're used to burning. Sun's"Burning"It is a nuclear fusion reaction process.

The sun fuses 600 million tons of hydrogen per second to form 100 million tons of helium, releasing the equivalent of 4 million tons of hydrogen. This process is similar to what we often call the hydrogen bomb, except that the energy released by our hydrogen bomb is uncontrollable, and the amount of energy released by the hydrogen bomb is limited.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to my auction, thank you.

Because the sun itself has energy, the energy of the sun is very huge, so it will continue to burn.

This is because there is a lot of hydrogen on the surface of the sun, and the reaction of nuclear fusion has taken place, so it will continue to burn.

Introduction: The Sun is the only star in the solar system, and the Sun is the only object in the solar system that can emit light and heat, and it needs oxygen in people's daily life, especially in the burning phenomenon of the earth. But why does the sun continue to burn without oxygen?

There are many ways to generate heat energy, and for the sun it continues to glow, and heat is not caused by combustion, but by nuclear fusion, which is mainly the fusion of hydrogen. Hydrogen can produce a large amount of energy in the process of fusion, and hydrogen will further become helium, and helium will further fusion. Moreover, the hydrogen content in the sun is very high, so the occurrence of this fusion in one post, the sun itself is a huge reactor itself through continuous light and heat, and countless reactions are carried out in this reactor.

Therefore, the sun can shine for a long time and can provide corresponding temperatures for other planets. The oxygen required for combustion is mainly the oxidation reaction that people are exposed to in their daily lives. Therefore, there are some phenomena in daily life that seem to be similar, but the essence is completely different, and they cannot be generalized and should be discussed separately.

In such a situation, the source can effectively discover the law.

Solar energy is indeed a good renewable energy, through which people can be converted into electricity in time, but solar energy resources are different in different regions. Therefore, we need to find other renewable energy sources, so that we can promote the continuous progress of human society. With energy comes motivation, so that the cost of living in people's daily lives can be reduced.

In addition, the use of non-renewable energy should be controlled accordingly, and everyone should practice a low-carbon lifestyle. Low-carbon living can reduce greenhouse gas emissions, make one's own environment healthier, and change people's habits of hail and hunger.

The sun is a nuclear reaction, not an ordinary combustion, it does not need oxygen, and it can still carry out nuclear reactions.

Because the combustion of the sun is mainly due to nuclear fusion, it can continue to burn even if there is no yang energy at this time.

Because the sun doesn't need oxygen to burn, the sun itself is a very hot thing.
