The purpose of a cell (battery) is to: Question 2 options: store chemical energy and transfer it to thermal energy when a circuit is connected. store chemical energy only 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.

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

Explanation:

A battery (single cell) is a container made of one cell that can produce a particular amount of electrical energy when needed.

It works by converting chemical energy to electric energy which is then used as a power source.

It stores up chemical energy and when connected to an external circuit, it provides electrical energy (through the flow of electrical current) to the circuit.

A battery is usually made up of a positive electrode and a negative electrode.
