Chapter 18, Problem 10RAT

Why does a battery that has thick zinc walls last longer than one that has thin zinc walls?

  1. (a) Thick zinc walls prevent the battery from overheating.
  2. (b) Thick zinc walls prevent electrons from being lost into the surrounding environment.
  3. (c) Thick zinc walls hold in the battery acid longer.
  4. (d) The zinc walls are transformed into zinc ions as the battery provides electricity.
