What kind of nuclear transformation occurs when the sun occurs, whether the sun is nuclear fusion or

The energy of the sun comes from the center of the sun, where the temperature is 15 million degrees, which can transform four hydrogen atoms into one helium atom, called nuclear fusion, this process can release a huge amount of energy, which is transmitted from its core to its surface Because the sun is a massive celestial body, when such a celestial body is constantly shrinking and heating up, when it accumulates to a certain point, it will cause the solar matter to produce nuclear fusion to produce high temperature and radiate energy matter around it. The reason why the sun can radiate energy into space so long and violently is because it has a large amount of material that can be used for nuclear fusion. When this material burns out, the Sun collapses into a white dwarf-like object.

The sun's energy will gradually disappear.

The sun is nuclear fusion.

The Sun uses the proton-proton cycle, one of the pathways by which four hydrogen nuclei fuse into a helium nucleus, a reaction process that is a small-mass, low-luminosity main-sequence star.

For example, more than 90% of the energy radiated by the Sun at this stage is provided by proton-proton reactions.

Nuclear fusion is also known as nuclear fusion, fusion reaction, fusion reaction.

or thermonuclear reactions, atomic nuclei.

There is a huge amount of energy in it, and the change of the nucleus (from one nucleus to another) is often accompanied by the release of energy.

The conditions under which nuclear fusion occurs

The conditions required to produce nuclear fusion are very demanding. The sun, for example, has a central temperature of 15 million degrees Celsius, and there is a huge amount of pressure to allow nuclear fusion to take place normally. And the earth can't get that much pressure, so it can only be compensated by raising the temperature, but then the temperature will have to reach hundreds of millions of degrees.

Nuclear fusion is so high that no solid substance can withstand it, and it can only be confined by a strong magnetic field. If high-temperature superconductors can be really put into practical use, they can solve the problem of magnetic fields, but the volume will inevitably be huge.

Nuclear fusion, the sun, as the most important energy of the solar system**, is constantly undergoing nuclear fusion inside it. The current sun is a yellow dwarf star entering middle age, and the main "hydrogen-helium nuclear fusion" occurs inside, and hydrogen elements form helium through nuclear fusion, which lights up the entire planet through nuclear fusion reactions and emits light and heat to the solar system.

Why is the sun able to gather a large amount of hydrogen to form hydrogen-helium nuclear fusion?

A healthy star needs to have a large amount of hydrogen as fuel for nuclear fusion, and these fuels are basically the nebulae that form galaxies.

Nebulae are often formed as a result of supernova explosions, which contain abundant elements, and with supernova explosions, heavy elements with higher specific gravity are thrown farther away, such as gold; Light elements with a smaller specific gravity will remain nearby to form nebulae, such as hydrogen and helium.

With the action of gravitation, hydrogen elements are gradually gathered in the center of the nebula to form a primordial star, and the accumulation and friction of material energy make the temperature inside the primordial star gradually increase, and when the temperature reaches the trigger point of hydrogen helium nuclear fusion, the star will be officially born!

Scientists have always dreamed of mastering controlled nuclear fusion, if controlled nuclear fusion can be carried out on the earth, then it is possible to create human beings own "artificial sun", using nuclear fusion technology, energy can be obtained directly from the elements, and it is a very large energy source, enough for mankind to enter a new era of energy!

However, until now, controlled nuclear fusion has been an unsolvable problem, and the result of uncontrollable nuclear fusion is the familiar hydrogen bomb. Nuclear fusion leads to the gradual development of elements into heavy elements, and nuclear fusion to calcium-iron nuclear fusion, and the star faces its final stage, collapsing into a white dwarf, neutron star, or black hole.

Correct answer: d

Many people should be aware of solar nuclear fission. Solar nuclear fission actually refers to the continuous nuclear fusion of the sun, which produces a lot of heat and light. And the sun is undergoing nuclear fission all the time, which is why we can feel the heat and light energy of the sun every day.

Nuclear fission is the phenomenon of nuclear fission occurs after a collision between atoms under conditions of ultra-high temperature and high pressure, and the surrounding environment must be focal. At the same time, in this process, very strong energy will be emitted, which mainly comes from the nucleus, and the release of this energy is often released due to the occurrence of nuclear fission.

The main hidden waters of solar nuclear fission have three forms: gravitational field constraint, inertial constraint, and magnetic constraint. When the sun undergoes nuclear fission, it has a certain impact on some surrounding planets or organisms. Many people have no possibility of nuclear fission on the earth, because nuclear fission requires a temperature of more than 100 million degrees, and the temperature of the earth will not be so high, and if there is, it will only be in the core.

A lot of the earth's energy comes from the sun, if there is no sun, the earth is dark, after the sun has nuclear fission, light and heat energy are of great significance to the earth. The sun also has an important impact on the earth all the time, and when the sun undergoes nuclear fission, it will affect many of our electronic devices, resulting in no signal on mobile phones, and it will also have an impact on many measuring devices.

Many years ago, a U.S. planet was destroyed by a storm over the Earth, and scientists concluded that nuclear fission was the cause of nuclear fission in the sun. If this storm had been earlier, it would have caused paralysis of many equipment on the earth, large-scale power outages, communication interruptions, and the losses caused would have been very large, and the nuclear fission of the sun would still have a very big impact on the earth.
