Nuclear Fusion

Nuclear fusion is the phenomenon in which multiple atomic nuclei combine to form a single, larger nucleus. Fusion mostly occurs under extreme conditions, due to the large amount of energy it requires. Thus, examples of fusion tend to be exotic; such as stellar nucleosynthesis, the creation of new elements, and thermonuclear weapons.

How does nuclear fission related from nuclear fusion?

User Avatar

Asked by Wiki User

Nuclear fission is the process of splitting a large atomic nucleus into smaller ones, releasing energy. Nuclear fusion, on the other hand, is when atomic nuclei combine to form a heavier nucleus, also releasing energy. Both processes release enormous energy but in different ways, with fusion being the process that powers the sun and stars.

Asked by Wiki User

In the sun, hydrogen atoms are fused together to create helium through a process called nuclear fusion. This fusion reaction releases a tremendous amount of energy in the form of light and heat, which powers the sun and sustains life on Earth.

Is nuclear fusion better than fission?

User Avatar

Asked by Wiki User

Nuclear fusion has the potential to be better than fission because it produces more energy, generates less radioactive waste, and uses abundant fuel sources like hydrogen isotopes. However, fusion technology is still in development and faces challenges in achieving sustainable reactions.

How does helium help us?

Asked by Wiki User

Helium is used in various ways, such as in cryogenics to cool superconducting magnets, in diving to reduce the risk of decompression sickness, in medical imaging like MRI machines, and in balloons for celebrations due to its lightness and non-flammability.

User Avatar

Asked by Wiki User

Some drawbacks of nuclear fusion include the high cost of research and development, the challenge of controlling the fusion reaction at high temperatures and pressures, and the potential risks associated with radioactive materials and waste management. Additionally, the technology is not yet commercially viable for large-scale energy production.

Differentiate nuclear fusion from nuclear fission using diagram?

User Avatar

Asked by Wiki User

Nuclear fusion involves combining atomic nuclei to create a heavier nucleus, releasing energy in the process. In contrast, nuclear fission involves splitting an atomic nucleus into smaller fragments, also releasing energy. In fusion, more energy is released compared to fission under the same conditions, but fusion reactions are more difficult to initiate and control.

What is a major disadvantage of using nuclear fusion reactors?

User Avatar

Asked by Wiki User

One major disadvantage of using nuclear fusion reactors is the challenge of controlling and sustaining the extreme conditions required for fusion reactions to occur, such as high temperatures and pressures. Additionally, the technology is still in the developmental stage and has not yet been deployed on a large scale for energy production.

Distinguish between nuclear fission and nuclear fusion?

User Avatar

Asked by Wiki User

Nuclear fission is the splitting of an atomic nucleus into smaller parts, releasing energy. It is the process used in nuclear power plants and atomic bombs. Nuclear fusion is the combining of two atomic nuclei to form a heavier nucleus, also releasing energy. It is the process that powers the sun and hydrogen bombs.

Nuclear fusion on the sun changes hydrogen into?

Asked by Wiki User

Nuclear fusion on the sun changes hydrogen into helium. This process releases energy in the form of light and heat. It is the source of the sun's power and the reason for its brightness and warmth.

How does fusion release energy?

User Avatar

Asked by Wiki User

Fusion releases energy when two light atomic nuclei combine to form a heavier nucleus. During this process, a small amount of mass is converted into a large amount of energy following Einstein's equation E=mc^2. This energy is released in the form of electromagnetic radiation such as gamma rays and kinetic energy of the particles involved.

Nuclear fusion has been researched for military applications, such as developing fusion-powered weapons or propulsion systems. However, there are no known operational military uses of nuclear fusion technology at present.

What happens to the matter that is consumed in nuclear fusion?

User Avatar

Asked by Wiki User

The matter that is "consumed" is converted into energy, according the the equation E=mc2.

The original matter mostly becomes the final matter, though a small amount is converted into heat. The amount converted into heat is small enough however, that the larger subatomic particles are all accounted for.

We could take as an example a fusion reaction in which a deuterium atom and a tritium atom are fused into helium. Deuterium and tritium are both isotopes of hydrogen, 2H and 3H respectively. The 2H nucleus consists of one proton and one neutron. The 3H nucleus consists of one proton and two neutrons. Each atom also has one electron. The total before fusion is two protons, two electrons, and three neutrons.

After the fusion takes place, the product is one helium atom, of the isotope 4He, plus one free neutron. The 4He atom has two protons and two neutrons, plus two electrons. Thus, the total of particles after fusion is two protons, two electrons, and three neutrons. In this case, however, the helium atom and the neutron are both very, very hot.

So the number of protons, neutrons, and electrons is the same after the reaction as it was before.

The equation on converting between energy and mass is E=mc2, as you know. The amount of energy released in the fusion example above is the difference between the mc2 before the reaction and the mc2 after the reaction. While this difference in mass is so small that it is not reflected in the counts of large subatomic particles, it is nonetheless there.

The masses, in Atomic Mass units, of the atoms and the neutron are:

at the beginning

2H - 2.014102

3H - 3.016049

which add to 5.030151

at the end

n - 1.008665

4He - 4.002602

which add to 5.011267

so the difference between the masses before and after the reaction is 0.018884 atomic mass units, which represents the amount of mass converted into energy in the reaction.

3 advantages nuclear fusion has over nuclear fission?

What is triple fusion?

User Avatar

Asked by Wiki User

Triple fusion is a process in plants where three individual nuclei from the male gamete (pollen) join together with two nuclei in the female gamete (ovule) during fertilization. This results in the formation of a triploid cell which eventually develops into the endosperm of the seed, providing essential nutrients for the growing embryo.
