B It changes back to chemical energy. n It is destroyed by the engine. D It is converted for the rest of the trip. When driving a car, the chemical energy in gasoline is converted to thermal energy in the engine. Most of this thermal energy is then converted to mechanical energy, which makes the car move. dune buggy chrome rear bumper
