Question

Statement A: For nuclear fusion to take place, a very high temperature is required.

Statement B: A hydrogen bomb is based on a nuclear fusion reaction

• A. Both statements A and B are true.
• B. Statement A is true. Statement B is false.
• C. Statement A is false, and statement B is true.
• D. Both statements A and B are false.

Answer 1

The correct option is A

Both statements A and B are true.

The explanation for Statement A:

1. Nuclear fusion is a process in which two light nuclei combine to form a heavy nucleus with the release of energy.
2. For example, four hydrogen atoms combine to form helium nuclei with the release of energy.
3. For fusion to take place, a very high temperature of the order of ${10}^{7}K$ is required.
4. The energy released per unit mass in fusion is greater than the energy released per unit mass in fission.

The explanation for Statement B:

1. Nuclear fusion is a process in which two light nuclei combine to form a heavy nucleus with the release of energy.
2. A hydrogen bomb is made up of two light nuclei i.e., deuterium and tritium which are fused to form a heavy nucleus i.e., helium and a neutron.
3. It is based on a nuclear fusion reaction as a large amount of nuclear energy is released by the fusion of the two light nuclei.

Hence, Both statements A and B are true.

Option (A) is the correct option.
