MCQ
Fusion reaction is also known as ..........:
- AChemical reaction
- BElastic reaction
- CThermonuclear reaction
- DPhotonuclear reaction
✓
Answer
- Thermonuclear reaction
Explanation:
In nuclear physics,nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at very high speed and join to form a new type of atomic nucleus. During this process matter is not conserved because some of the matter of fusing nuclei is converted to photons also known as thermonuclear reaction.
