Question
Explain why nuclear fusion requires very high temperatures.
Answer
Nuclear fusion requires very high temperatures to provide the necessary energy for the nuclei to overcome the electrostatic repulsion between them. At high temperatures, the kinetic energy of the particles increases, allowing them to collide with sufficient force to fuse together.
Explanation
This answer demonstrates an understanding of the fundamental concept of electrostatic forces and the conditions necessary for fusion to occur. It tests the student's ability to connect temperature with the energy needed for nuclear reactions.
Common mistake
Misunderstanding Fusion Temperature Requirements
Students often think that fusion can occur at normal temperatures without understanding the need for extremely high temperatures to overcome electrostatic repulsion between positively charged nuclei.
Emphasize that fusion requires very high temperatures, typically in the millions of degrees, to provide the necessary energy for nuclei to collide and fuse.
