| As the electrolyte level in the cells of a lead-acid battery evaporates over time, what will tend to happen to the specific gravity of the electrolyte in the cells as the level drops due to evaporation? |
| A) Although the specific gravity will change due to evaporation, there is no predictable tendency either way. |
| B) The specific gravity of the electrolyte will decrease as only the sulfuric acid will evaporate from the electrolyte solution. |
| C) The specific gravity of the electrolyte will remain unchanged as both the water and sulfuric acid will evaporate from the electrolyte solution. |
| D) The specific gravity of the electrolyte will increase as only the water will evaporate from the electrolyte solution. |
