Formation of large molecule by joining small molecules is_________________?
Correct answer: B. Polymerization
- A. Fusion
- B. Polymerization
- C. Crystallization
- D. Subtraction
Explanation
Polymerization joins many small molecules called monomers to form a large molecule called a polymer. Fusion, the likely mistaken choice, refers to joining atomic nuclei or melting materials, not normally to forming polymers from monomers.

About Energy Losses and Efficiency
Efficiency compares useful output energy or power with the total input, usually expressed as a percentage. The topic covers energy losses through friction, heating, resistance and sound, along with power ratings and Sankey diagrams. Efficiency is not the same as conservation of energy, because lost energy is transferred rather than destroyed.
