Answer 2

★★★★★★★★★★★★★★★★★★★★★★★★
A battery has stored chemical energy. The chemical energy is converted into electrical energy during lighting of bulb. So, a battery converts chemical energy into electrical energy. The filament in the bulb becomes white hot and gives out light. Electrical energy is converted into heat and light energy.

Thus, the energy changes involved in this process can be written as follows:

Chemical energy —> Electrical energy —> Heat energy + Light energy.
