Match the following Columns
| Column I | Column II |
|---|---|
| (A) Nuclear fusion | (P) Converts some matter into energy |
| (B) Nuclear fission | (Q) Generally possible for nuclei with low atomic number |
| (C) -decay | (R) Generally possible for nuclei with higher atomic number |
| (D) Exothermic nuclear reaction | (S) Essentially proceeds by weak nuclear forces |
Answer: A → I, A → II, B → I, B → III, C → I, C → IV, D → I, D → II, D → III
Solution
(A) Nuclear fusion: Combines light nuclei (low atomic number) and converts mass to energy. Matches (P) and (Q).
(B) Nuclear fission: Splits heavy nuclei (high atomic number) and converts mass to energy. Matches (P) and (R).
(C) β-decay: Mediated by weak nuclear force, converts mass to energy. Matches (S) and (P).
(D) Exothermic nuclear reaction: Releases energy by converting mass to energy; includes both fusion (low Z) and fission (high Z). Matches (P), (Q), and (R).
Pairs: (A)→(P),(Q), (B)→(P),(R), (C)→(S),(P), (D)→(P),(Q),(R)
