Question

The purpose of a cell (battery) is to:
Question 2 options:

store chemical energy only when a circuit is connected.

store chemical energy and transfer it to thermal energy when a circuit is connected.

store chemical energy and transfer it to electrical energy when a circuit is connected.

release chemical energy and absorb thermal energy when a circuit is connected.

Answer 1

well, you use batteries to power **electrical** devices, right? so eliminate D (they don't absorb thermal energy) and B (I guess you could argue that batteries do produce thermal energy but that's not their purpose)

so between A and C, which one is a better description of what a battery does?
