Question

Fusion reaction takes place at high temperature because:

• A. atoms are ionised at high temperature
• B. molecules break up at high temperature
• C. nuclei break up at high temperature
• D. kinetic energy is high enough to overcome repulsion between nuclei

Answer 1

The correct option is D kinetic energy is high enough to overcome repulsion between nuclei

In nuclear fusion reaction, the lighter nuclei combine together to form heavier nuclie.

Fusion reaction takes place at high temperature because kinetic energy is high enough to overcome repulsion between nuclei.
