Nuclear fission and fusion
Question
- A. Fusion requires low temperatures to occur
- B. Fusion is the energy source of stars
- C. Fusion produces radioactive waste
- D. Fusion is easier to achieve than fission
Answer
Fusion is the energy source of stars
Explanation
Nuclear fusion is the process that powers stars, including our sun, by fusing hydrogen nuclei into helium under extreme temperatures and pressures.
Common mistake
Misunderstanding Electrostatic Repulsion
Students often think that high temperature is solely needed for fusion to occur without understanding that it specifically overcomes the electrostatic repulsion between positively charged nuclei.
Emphasize that high temperature provides the kinetic energy necessary for nuclei to collide with enough force to overcome their repulsive forces, enabling fusion.
