1.ELECTRICAL ENERGY —> CHEMICAL ENERGY —> ELECTRICAL ENERGY —> SOUND ENERGY
(When charging your laptop electrical energy from plugging in the charger turns into chemical energy inside the laptop. Chemical energy turns into electrical energy when you begin to use the laptop. Sound energy is produced when you turn on the laptop and hear a noise.)
2.CHEMICAL POTENTIAL ENERGY —> ELECTRICAL ENERGY —> KINETIC ENERGY
(It transforms chemical potential energy into electrical energy and then into kinetic energy.)
3.CHEMICAL ENERGY —> HEAT
(Chemical energy is stored in the hydrocarbon molecules in the coal. When the coal is combusted, this chemical energy is transformed into heat.)
4.ELECTRICAL ENERGY —> MECHANICAL ENERGY —> THERMAL/HEAT ENERGY
(Electrical (and light) energy from the lightning is converted into mechanical energy that causes the tree to split and thermal energy in the form of heat.)
5.ELECTRICAL ENERGY —> LIGHT ENERGY —> THERMAL ENERGY
(In a flashlight, the electrical energy becomes light energy and thermal energy in the bulb.
