The core of the protostar reached an extremely high temperature
Nuclear fusion takes place only in the core of the Sun, or any star. Extremely high energy (temperatures) are required to force atomic nuclei together. The fusion reaction releases heat energy, which continues the fusion of other nuclei.
Only at the core, where the temperatures and pressures are high enough.
It is the process that produces all the sun's energy
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.
Nuclear fusion requires extremely high temperature and great pressure.
Nuclear fusion requires extremely high temperature and great pressure.
The Sun is powered by nuclear fusion which requires extremely high temperatures to happen. Hydrogen is fused into helium releasing incredible amounts of energy which is counteracted by gravity.
Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.
The core of the protostar reached an extremely high temperature
Thermonuclear Fusion - Nuclear fusion brought about by high temperatures
Fission. Fusion can be achieved at room temperature and pressure , Fission (seems to) requires extremely high temps and pressures.
Nuclear fusion requires very high temperatures and immense pressures to start and continue. The problems with a nuclear fusion reactor would be:- 1) the high temperatures would melt the container: therefore, the reaction would have to be stored in a vacuum suspended by a magnetic field and the reactor would have to be continually cooled. 2) nuclear fusion occurs naturally in stars such as our sun: unless the fusion reaction was limited in size in some way, it would be likely that our planet is vapourised by the reaction.
Nuclear fusion takes place only in the core of the Sun, or any star. Extremely high energy (temperatures) are required to force atomic nuclei together. The fusion reaction releases heat energy, which continues the fusion of other nuclei.
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
Nuclear fusion is based on the helium nucleus synthesis from two hydrogen atoms at very high temperatures.
Nuclear fusion of light elements is the process operating in the stars to produce energy, and needs very high temperature to occur. Experiments on earth to aim at producing useful power from fusion have been progressing for many years. The reactants most likely to be used are isotopes of hydrogen, deuterium and tritium. These need to be heated to some hundreds of millions of degrees kelvin before reaction starts. Fusion reactions have been seen, but only for less than 1 second so far. Fusion is not a chemical reaction, it is a nuclear process.
