Which type of nuclear process requires an extremely high temperature (millions of degrees)

Question

Quizplus · Accepted Answer

Fusion reaction requires extremely high temperatures (millions of degrees) to overcome the electrostatic repulsion between positively charged atomic nuclei and fuse them together. Beta decay, alpha decay, and positron emission are all examples of radioactive decay, which do not require such high temperatures. Fission reaction, while it does require a certain amount of energy to initiate, does not require millions of degrees of heat.
