MCQ
Fusion reaction takes place at high temperature because 
  • A
    nuclei break up at high temperature
  • B
    atoms get ionised at high temperature
  • kinetic energy is high enough to overcome the coulomb repulsion between nuclei
  • D
    molecules break up at high temperature

Answer

Correct option: C.
kinetic energy is high enough to overcome the coulomb repulsion between nuclei
c
Extremely high temperature needed for fusion make kinetic energy large enough to overcome coulomb repulsion between nuclei.
