What is the source of energy for a star?
The energy source for stars, which produces vast amounts of heat and light, is the fusion of atomic nuclei in the star's core. In our own Sun, hydrogen is fused into helium; in older and heavier stars heavier elements may also undergo nuclear fusion.
Why does a star produce light?
Because of nuclear fusion! The nuclear fusion releases energy which produces light.
What type of reaction happening in sun when it emits heat and light?
The most common sun reaction that happens in the sun is the hydrogen fusion. Other fusions like complex fusions among nuclei of carbon, nitrogen, and oxygen atoms also produce energy in the sun.
Does the sun produce light or reflect light?
The sun makes light through fusion The moon reflects light
What is the source of heat and light of the sun?
The answer is Nuclear Fusion
What is The combining of light nuclei is called?
fusion
What is the combining of light weight nuclei into heavier nuclei that gives off energy that fuels the Sun?
fusion
What the combining of atomic nuclei is?
The combination of two light atomic nuclei to form a heavier nucleus is called fusion.
The binding together of two light nuclei to form a heavier one is called what?
its fusion
What is the difference between fusion and fission atomic bombs?
Good question. A fusion bomb combines (fuses) light nuclei (hydrogen) into larger nuclei to get its energy. But it needs a fission bomb to start it. A fission bomb breaks up (fissions) heavy nuclei (uranium/plutonium) into smaller nuclei to get its energy.
Compare and contrast fusion and fission?
With nuclear fission, a large atomic nucleus (such as a uranium nucleus) breaks apart into smaller nuclei, and energy is released. With nuclear fusion, small atomic nuclei (such as hydrogen) join to become larger nuclei, and energy is released. Fusion of hydrogen releases much more energy than any other type of either fusion or fission. Note that the dividing line between heavy nuclei and light nuclei is the iron nucleus, which is at the perfect point of nuclear stability, so that neither fusion nor fission of iron nuclei would release any energy.
The binding together of two light nuclei to form a heavier one is called?
A reaction in which small nuclei combine to form a heavier nucleus is called a nuclear fusion reaction. Large amounts of energy are required for fusion to happen but it will release even larger amounts of energy.
What does nuclear fusion mean?
Nuclear fusion refers to a nuclear reaction wherein two light nuclei fuse to form a heavier nucleus. This process releases energy.
Does fusion and fission began with uranium?
No... Nuclear energy can be produced either by the fusion of 2 lighter nuclei or the fission of a heavier nucleus into 2 aprox equal nuclei by mass. Since Uranium has a very heavy nucleus, it can only undergo fission and not fusion. For generating energy through fusion, Hydrogen nuclei were the first to be used and are primarily preferred since hydrogen has a very light nucleus. Hydrogen fusion is what is the source of energy of the Sun and thus, the origin of the notion of nuclear fusion. The amount of energy produced by any nuclear reaction is given by Einsteins famous mass-energy relation - E=mc2 where c is the speed of light and m is the mass disappeared after the reaction.. NAMAN
Why is the sun's temperature so high?
Because of the Thermonuclear fusion that goes on inside the core. Hydrogen nuclei undergo this process to form helium nuclei, giving out massive amounts of heat and light.
What did nuclear weapons evolve from?
Nuclear weapons did not evolve! They were invented by people based on newly discovered natural phenomena of the atomic nucleus (e.g. the neutron, fission of heavy nuclei, fusion of light nuclei). The first invention was in 1933 by Leo Szilard while living in London, of the neutron chain reaction. But it took many other inventions before the first atomic fission bombs could be built in 1945 and the first hydrogen fusion bomb in 1952.
What are the 3 main types of nuclear reactions?
Nuclear fission: When an element breaks apart to form lighter elements and other sub-atomic particles. Nuclear fusion: When two lighter elements fuse to form heavier ones.
