Fusion reaction takes place at high temperaturebecause [2011]
- a)nuclei break up at high temperature
- b)atoms get ionised at high temperature
- c)kinetic energy is high enough to overcomethe coulomb repulsion between nuclei
- d)molecules break up at high temperature
Correct answer is option 'C'. Can you explain this answer?

Understanding Fusion Reactions
Fusion reactions, which power stars including our Sun, require extremely high temperatures to occur. The primary reason for this is the need to overcome electrostatic forces between positively charged atomic nuclei.
Key Factors in Fusion:
The Fusion Process:
Conclusion:
To summarize, the correct answer is option 'C' because high temperatures provide the necessary kinetic energy to overcome the Coulomb repulsion between nuclei, enabling fusion to occur.
Fusion reactions, which power stars including our Sun, require extremely high temperatures to occur. The primary reason for this is the need to overcome electrostatic forces between positively charged atomic nuclei.
Key Factors in Fusion:
- High Temperatures: At temperatures exceeding millions of degrees Celsius, such as those found in stellar cores, particles gain significant kinetic energy.
- Coulomb Repulsion: Nuclei are positively charged due to protons, causing them to repel each other due to the Coulomb force. This repulsion must be overcome for fusion to take place.
- Kinetic Energy: Increased kinetic energy at high temperatures allows nuclei to collide with sufficient energy to overcome this repulsive force, bringing them close enough for the strong nuclear force to take over, leading to fusion.
The Fusion Process:
- Initiation: When two light nuclei, such as isotopes of hydrogen (deuterium and tritium), collide at high velocities, the kinetic energy enables them to overcome their mutual repulsion.
- Fusion: Once the nuclei are close enough, the strong nuclear force binds them together, resulting in the formation of a heavier nucleus and the release of vast amounts of energy.
- Energy Release: This energy is not only the reason why fusion is so powerful but also what fuels stellar processes and contributes to the light and heat emitted by stars.
Conclusion:
To summarize, the correct answer is option 'C' because high temperatures provide the necessary kinetic energy to overcome the Coulomb repulsion between nuclei, enabling fusion to occur.
