Best answer: How does nuclear fusion generate energy quizlet?

Creation of energy by joining the nuclei of two hydrogen atoms to form helium. A nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy.

How does nuclear fusion produce energy?

Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

What is a nuclear fusion quizlet?

nuclear fusion. the process in which two or more atomic nuclei join together, or “fuse”, to form a single heavier nucleus. This is usually accompanied by the release or absorption of large quantities of energy.

How does nuclear fusion make life on Earth possible quizlet?

How does this phenomenon make life on Earth possible? It creates the magnetosphere, which diverts high-energy particles from space away from Earth’s surface. Earth’s magnetosphere is not uniformly shaped. It is compressed on the side facing the Sun and has a long tail extending away from the Sun.

What is the benefit of producing energy from fusion quizlet?

Fusion produces large amounts of energy, and the fuel is found on Earth. Fusion produces no radioactive waste, and the fuel is plentiful. Fusion requires little energy to begin and would continue through a chain reaction.

Why is fusion so hard?

Because fusion requires such extreme conditions, “if something goes wrong, then it stops. No heat lingers after the fact.” With fission, uranium is split apart, so the atoms are radioactive and generate heat, even when the fission ends. Despite its many benefits, however, fusion power is an arduous source to achieve.

Is nuclear fusion difficult to control?

Fusion, on the other hand, is very difficult. Instead of shooting a neutron at an atom to start the process, you have to get two positively charged nuclei close enough together to get them to fuse. … This is why fusion is difficult and fission is relatively simple (but still actually difficult).

Why is nuclear fusion of interest today?

In contrast to nuclear fission, which results in smaller isotopes being formed from larger ones, the goal of nuclear fusion is to produce larger materials from the collision of smaller atoms. … Nuclear fusion reaction between deuterium and tritium. This release of energy is what drives research on fusion reactors today.

What is the difference and similarities between nuclear fission and nuclear fusion?

Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

Where does nuclear fusion take place quizlet?

Nuclear fusion reactions occur in the Sun and supply the energy needed to sustain life on Earth. When two nuclei join together, the mass of the product nucleus is less than the sum of the masses of the original nuclei.

How does nuclear fusion make life on earth possible?

Explanation: Nuclear fusion is the process by which the Sun produces its energy. It converts mass into energy, which is radiated over most of our solar system. … Without the Sun’s energy, in the amount we receive, the Earth would likely be entirely frozen and beyond deathly cold.

Why can nuclear fusion occur in the core of a star quizlet?

A protostar becomes a star when nuclear fusion begins in the core. … As the star collapses, the pressure and temperature rise until it is high enough for helium to fuse into carbon, i.e. helium burning begins. To radiate the energy produced by the helium burning, the star expands into a Red Giant.
