MCQ

Fusion reaction takes place at high temperature because

A
Molecules break up at high temperature
B
Nuclei break up at high temperature
C
Atoms get ionised at high temperature
✓
Kinetic energy is high enough to overcome the coulomb repulsion between nuclei

✓

Answer

Correct option: D.

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

d
In nuclear fusion reaction, the lighter nuclei combine together to form heavier nuclie.

Fusion reaction takes place at high temperature because kinetic energy is high enough to overcome repulsion between nuclei.

Wave property of electrons implies that they will show diffraction effects. Davisson and Germer demonstrated this by diffracting electrons from crystals. The law governing the diffraction from a crystal is obtained by requiring that electron waves reflected from the planes of atoms in a crystal interfere constructively (see figure).
