Thermonuclear fusion is responsible for sunshine. Thermonuclear reactions take place at very high temperatures. In the Sun, hydrogen atoms fuse together to form helium atoms. In this process radiant energy is produced and reaches the Earth.
Is the Sun an example of fusion or fission?
The source of the sun’s energy is Nuclear Fusion 🙂 Basically, the heat generated within the sun causes the nuclei which would normally repel one another (because they both have a positive charge) to bang into one another and fuse. As a result of the fusion, a new atom is created.
What kind of nuclear power is responsible for sunshine quizlet?
The high-energy neutrons will escape from the plasma in the reactor vessel and heat a surrounding blanket of material to provide useful energy. The helium nuclei that remain behind will help to keep the plasma hot. What kind of nuclear power is responsible for sunshine? Fusion: proton + deuteron produces helium-3.
Which type of nuclear reaction is a source of energy that powers the Sun?
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.
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).
Is work required to pull a nucleon out of an atomic nucleus?
Work is required to pull a nucleon out of a atomic nucleus, it has more mass when it comes out. How does the mass per nucleon in uranium compare with the mass per nucleon in the fission fragments of uranium? The mass of the nucleons is the same, but their binding energy is different.
Why does a neutron make a better nuclear bullet?
Why does a neutron make a better nuclear bullet than a proton? neutrons are better bullets because they have no charge and are not repelled by protons in the nucleus which they are aimed at. … The neutron has no charge and the same mass as the proton and it has strong interactions, so it is a better choice.
Is the sun nuclear?
The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second.
What are the 3 conditions needed for nuclear fusion?
High pressure squeezes the hydrogen atoms together. They must be within 1×10–15 meters of each other to fuse. The sun uses its mass and the force of gravity to squeeze hydrogen atoms together in its core. We must squeeze hydrogen atoms together by using intense magnetic fields, powerful lasers or ion beams.
