Atoms and Nuclei question

2011 · Q140

NEETPhysicsAtoms and NucleiMCQ+4 / −1
Fusion reaction takes place at high temperature because
  1. A
    nuclei break up at high temperature
  2. B
    atoms get ionised at high temperature
  3. C
    kinetic energy is high enough to overcome the coulomb repulsion between nuclei
  4. D
    molecules break up at high temperature
View written solutionFree

Correct answer: C

Extremely high temperature needed for fusion make kinetic energy large enough to overcome coulomb repulsion between nuclei.
