What happens when gasoline is burned in a car engine?

Back

When gasoline is burned in a car engine, chemical energy is transformed into mechanical energy, which powers the car.

How does a lamp work?

Back

A lamp transforms electrical energy into thermal energy (heat) and light energy, causing the bulb to glow.
