What is the standard temperature to start hydrogen fusion?

WebNuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons).The difference in mass between the … WebAt some point, the helium core reaches a density and temperature at which the triple-alpha process starts to fuse helium into carbon. This reaction (as you may recall) is VERY sensitive to temperature: So, when the reactions begin, they produce energy, which raises the temperature of the helium core. cheverus school teacher page mrs.malatesta https://videotimesas.com
