Question

How does nuclear fusion differ fundamentally from nuclear fission? Nuclear fusion combines atomic nuclei. Nuclear fusion doesn’t produce energy. Nuclear fusion is a cold process. Nuclear fusion splits atomic nuclei.

Answer 1

A) Nuclear fusion combines atomic nuclei.

Answer 2

Nuclear fusion combines atomic nuclei.

Step-by-step explanation:

The main difference between nuclear fusion and fission is that nuclear fusion involves fusion of 2 smaller nuclei into a bigger nuclei. Nuclear fission on the other hand involves fission/splitting of a large radioactive nucleus into smaller nuclei which are comparatively stable.

Option 2nd is incorrect because nuclear fusion produces huge amount of energy more than even nuclear fission. Option 3rd is also incorrect because nuclear fusion is a real process not a cold process which is considered as hypothetical. Option 4th is also incorrect because nuclear fusion is a process in which 2 hydrogen nuclei fuse to form a helium nucleus which is bigger in size. That means fusion does not involve splitting of atomic nuclei.
