Question

Quizplus · Accepted Answer

The critical temperature for the core to shine by fusion is about 10 million Kelvin, which is the temperature required for hydrogen ions to overcome their electrostatic repulsion and collide with enough energy to fuse into helium. The critical temperature the core must reach for a star to shine by fusion is around 10 million K. At this temperature, hydrogen undergoes nuclear fusion to form helium, releasing a tremendous amount of energy.
