JEE · NEET Previous Year Question

$Fusion reaction takes place at high temperature because$

Topic: NEET PYQ

Answer: C. Full step-by-step solution below.

A $nuclei break up at high temperature$
B $atoms get ionized at high temperature$
C $kinetic energy is high enough to overcome the coulomb repulsion between nuclei$
D $molecules break up at high temperature$

Correct answer: C

Solution

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