(a) What is nuclear fusion ? Explain with an example. Write the equation of the reaction involved.
(b) Why are very high temperature required for fusion to occur ?

Options

A. At high temperature, kinetic energy is sufficient to overcome repulsive force
B. Atoms are ionised at high temperature
C. Molecules break up at high temperature
D. Nuclei break up at high temperature

Answer

A

Explanation

For fusion high temperature of the order of `10^(7)K " to " 10^(8)K` is required.
