Physics Question on Nuclei
Fusion reaction takes place at high temperature because
A
nuclei break up at high temperature
B
atoms get ionised at high temperature
C
kinetic energy is high enough to overcome the coulomb repulsion between nuclei
D
molecules break up at high temperature
Answer
kinetic energy is high enough to overcome the coulomb repulsion between nuclei
Explanation
Solution
Coulomb resistance between nuclei can be overcome because of the large kinetic energy.
In order to overcome the coulomb repulsion between nuclei as two lighter nuclei join to produce a heavier nucleus, high temperature, and high pressure are necessary.
