Respuesta :
The difference is that in a nuclear reactor it uses normal pressures and temperatures that are relative to earth using fission , where as in the sun, fusion happens and with that comes extremely high temperatures and bone squishing pressures.
Nuclear reaction is "a process in which two nucleus and an external subatomic particle, collide to produce one or more new nuclides".
Nuclear reactions are of two types,
- Nuclear fusion reaction and
- Nuclear fission reaction
What is nucleus?
Nucleus is a collection of particles called protons and neutrons.
What is subatomic particles?
Subatomic particles are "particles which are smaller than an atom in size".
What are nuclides?
Nuclides are "the nuclei of atoms of a specific isotope".
What is nuclear fusion reaction?
In nuclear fusion reaction, "two light nuclei merge to form a single heavier nucleus".
What is nuclear fission reaction?
Nuclear fission reaction "is a process in which an unstable nucleus splits into two nuclides and emits neutrons".
Therefore, the nuclear reaction that take place in the sun is nuclear fusion reaction and the nuclear reaction taking place in the nuclear reactor is nuclear fission reaction.
