Which type of nuclear process requires an extremely high temperature (millions of degrees)?
A) Beta decay

C) Fusion reaction
D) Alpha decay
E) Positron emission

Question

Quizplus · Accepted Answer

Fusion reaction requires an extremely high temperature (millions of degrees) to overcome the repulsive forces between two positively charged nuclei and allow them to come together and merge into a single, heavier nucleus. This process is what powers the sun and other stars. Beta decay, alpha decay, and positron emission are all forms of radioactive decay that do not require such high temperatures. Fission reactions can occur at lower temperatures, but still require significant amounts of energy to split heavy nuclei.
