Fusion reaction takes place at high temperature because

A

nuclei break up at high temperature

B

atoms get ioniside at high temperature

kinetic energy is high enough to overcome the coulomb repulsion between nuclei

D

molecule break up at high temperature

Text Solution

Verified by Experts

The correct Answer is:
