Which statement correctly identifies how a lead-storage battery in a car works?
A. The battery acts as a galvanic cell as it provides current to the radio.
B. The battery acts as a galvanic cell as it is recharged by the alternator.
C. The battery acts as an electrolytic cell as it starts the car.
D. The battery acts as an electrolytic cell as it powers the headlights.
I think the answer is either a or b.
I think A is the answer although it isn't stated very well. It also acts as a galvanic cell for everything else it runs in the car including starting the engine etc.
I didn't choose B because when it is being recharged by the alternator in the car it is acting as an electrolytic cell; i.e., it isn't running anything so it isn't acting as a galvanic cell.
Well, I guess you can say a lead-storage battery in a car is a real "power-player." It actually acts as a galvanic cell as it is recharged by the alternator. So, option B is the correct one! It's like the battery is getting its energy boost from the alternator, keeping everything charged up and ready to go, just like an energy drink for your car!
The correct statement is B. The lead-storage battery in a car acts as a galvanic cell as it is recharged by the alternator.
To determine the correct statement about how a lead-storage battery in a car works, let's break down the given options:
A. The battery acts as a galvanic cell as it provides current to the radio.
B. The battery acts as a galvanic cell as it is recharged by the alternator.
C. The battery acts as an electrolytic cell as it starts the car.
D. The battery acts as an electrolytic cell as it powers the headlights.
A galvanic cell is an electrochemical cell where the conversion of chemical energy into electrical energy takes place spontaneously. On the other hand, an electrolytic cell is an electrochemical cell that uses an external source of electrical energy to facilitate a non-spontaneous chemical reaction.
Considering these definitions, we can eliminate options C and D since they both describe the battery acting as an electrolytic cell, which is not the case for a lead-storage battery in a car.
Now, let's focus on options A and B:
A. The battery acts as a galvanic cell as it provides current to the radio.
This statement implies that the battery is providing current (electricity) to power the radio in a spontaneous manner, which aligns with how a lead-storage battery functions.
B. The battery acts as a galvanic cell as it is recharged by the alternator.
This statement suggests that the battery is being recharged by the alternator, which contradicts the typical operation of a lead-storage battery. Lead-storage batteries are not typically recharged using a galvanic cell process but rather through the alternator and the charging system of a car.
Based on this analysis, the correct statement should be:
A. The battery acts as a galvanic cell as it provides current to the radio.
Therefore, option A is the correct choice.
