Web11 jun. 2024 · Once the core is degenerate, it will continue to heat until it reaches a temperature of roughly 108 K, hot enough to begin fusing helium to carbon via the triple-alpha process. When the degenerate …
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
What temperature does hydrogen fuse into helium? - Studybuff
WebOnce the core reaches a temperature of about 100 million Kelvin Helium fusion starts dramatically (Helium Flash) with high radiation pressure in the core. Here is where the Sun will reach 250 times it's current radius. When the Helium fusion stabilizes the radiation pressure at the cores decreases making the Sun's radius to shrink.
