Chapter 19.3, Problem 1RQ

Interpretation Introduction

Interpretation:

Difference between the fission and fusion is to be explained.

Concept introduction:

Nuclear fission and nuclear fusion both the nuclear reaction because both release the energy but their uses are quite different from each other.

Answer to Problem 1RQ

The difference between the fusion and fission is that nuclear fission involves the dissociation of a heavy unstable nucleus into lighter nuclei while nuclear fusion involves the integration of two lighter nuclei into a heavy nucleus.

Explanation of Solution

The main difference between the fusion and fission is that the word fusion means to combine and the word fission means breakdown. So, the fission is that nuclear reaction in which an unstable heavy nucleus is breakdown in to two or lighter nuclei on the other hand the fusion is that nuclear reaction in which two lighter nuclei are combining with each other and forms a stable heavy nucleus.

Conclusion

Fission involves the breaking of heavy nucleus into lighter nuclei while fusion is the combination of two lighter nuclei into a heavy nucleus and both reactions release the large amount of energy.
