Question

a battery light a bulb describe the energy changes involved in the process​

Answer 1

Answer:

When a battery lights a bulb, first energy transformation takes place in the battery and then in the bulb.

In the battery, the chemical energy gets converted into electrical energy.

Battery: Chemical energy → Electrical energy

In the bulb, the electrical energy from the bulb gets converted into heat energy and then into light energy.

Bulb: : Electrical energy → Heat energy → Light energy.

So, Energy Changes are

Chemical energy → Electrical energy → Heat energy → Light energy

Answer 2

A bulb uses electrical energy to light up its surroundings. A battery has chemicals inside it which can react with each other and generate electricity through the flow of electrons. Hence when a battery is connected with a bulb, its chemical potential energy is converted into electrical energy
