Question
- A. Rechargeable cells can be used multiple times, while non-rechargeable cells cannot.
- B. Non-rechargeable cells are larger than rechargeable cells.
- C. Rechargeable cells produce more heat than non-rechargeable cells.
- D. Non-rechargeable cells are always alkaline.
Answer
Rechargeable cells can be used multiple times, while non-rechargeable cells cannot.
Explanation
The key difference is that rechargeable cells can have their chemical reactions reversed and be reused, while non-rechargeable cells stop working once their reactants are depleted.
Common mistake
Misunderstanding Rechargeability
Students often think that rechargeable cells can be recharged indefinitely without any loss of capacity.
Explain that while rechargeable cells can be recharged multiple times, their capacity decreases over time due to chemical degradation.
