Is fusion or fission the main energy source for stars?
Nuclear Fusion
Nuclear fission where is it found?
stars.... stars are made of hydrogen, helium, and nuclear fusion
What does Nuclear Fusion have to do with stars?
The stars produce their heat from nuclear fusion reactions. Work on earth to produce controllable nuclear fusion is concentrating on one particular reaction, between deuterium and tritium, because it is the easiest to get going (though hard enough!). Stars operate with other reactions but all of the nuclear fusion type. You can read more in Wikipedia 'Nuclear fusion'
Do fusion reactions provide nuclear power?
No, a fission reaction is not necessary to trigger a fusion reaction, but for us on earth, it is. In the field of nuclear weapons, a fission bomb is needed to create the heat necessary to set off a fusion weapon. We have to use fission, or, rather, the energy created by that, to initiate the fusion reaction. It might be possible to use a high power source, like a laser, on a small amount of material to get fusion to occur. But we are still experimenting with this in the Tokamak, and it's far from being a done deal. Stars are, in general, massive nuclear fusion reactors. Their constant consumption of fuel powering their high rate of fusion creates a massive amount of energy, and the stars' huge gravity keeps this process from blowing the whole thing apart. No fission is needed to sustain this reaction.
Is there a place other then the Sun that nuclear reaction happens?
Yes - all the millions of other stars in the Universe, where fusion occurs. Also of course fission reactions in all nuclear reactors on earth
Is it true orFALSE that stars are powered by nuclear fusion reactions?
false
Which reactions is responsible for energy radiating from stars including the Sun?
Nuclear fusion
What is naturalization reaction?
Natural nuclear fusion reactions occur in all stars
What does nuclear fusion convert hydrogen into?
Nuclear reactions in the cores of stars convert hydrogen to helium
What is Alternative energy source produced from atomic reactions?
Nuclear fission is when a neutron is fired at an element with a high atomic number, which splits and releases more neutrons and energy as a result. Nuclear fusion occurs in stars and experimental reactors.
How do stars create all elements up to iron in their core. What if your answer?
The process is called stellar nucleosynthesis and is based on nuclear fusion reactions.
What is nuclear energy made from?
In general, nuclear energy comes from the energy associated with atomic nuclei. There is nuclear fusion, which happens in stars and in fusion weapons, and there is nuclear fission. Nuclear fusion is the "combining" of lighter atomic nuclei to create heavier ones, and many fusion reactions release energy. (Again, think of stars.) In contrast, nuclear fission is the "splitting" of atomic nuclei to release energy. The latter is technology that we've come to use fairly widely, and we have developed fission nuclear weapons and the nuclear reactor to tap nuclear energy via fission. Let's look at the latter device, the reactor. The fission of nuclear fuel (also known as atomic fuel, such as uranium or plutonium) is where we get nuclear energy. And what happens during nuclear fission is that the nuclei of fuel atoms absorb neutrons and fission (split), releasing lots of energy. In fission, that larger atomic nucleus breaks into a pair of smaller ones, and these fission fragments recoil with a lot of kinetic energy. The fuel traps the fission fragments, and the energy they came away with is converted into thermal energy in the fuel. We derive nuclear energy by tapping the energy of formation of atomic nuclei via fusion or fission. This is advanced technology that is less than a century old. We're still working to use it well and wisely.
