EVERYDAY SCIENCE

Detailed explanation-1: -In a flashlight, chemical energy in the batteries is converted to electrical energy when the circuit including the batteries, switch and light bulb is completed. The electrical energy is converted to light (electromagnetic / radiant energy) and some heat (thermal energy) by the light bulb.

Detailed explanation-2: -A campfire takes the chemical potential energy contained in wood and turns it into the radiant kinetic energy of heat and light.

Detailed explanation-3: -A battery is a device that stores chemical energy, and converts it to electricity. This is known as electrochemistry and the system that underpins a battery is called an electrochemical cell.

Detailed explanation-4: -Electrical energy A torch battery has chemical energy stored in it. When the battery is connected in a circuit, this chemical energy is changed into electrical energy, which is then carried by the electricity from the battery to a light globe where it can be changed into light.
