Question

which best describes how energy changes form in a cars engine? a single transformation occurs because the chemical energy of the fuel is changed to the mechanical energy of the car. a single transformation occurs because the mechanical energy of the car originates from one spark. multiple transformations occurs because the chemical energy of the fuel is changed to several forms of energy. multiple transformations occur because the chemical energy of the fuel must be replenished to keep the car running.

Explanation:

In a car engine, fuel's chemical energy is converted not just to mechanical energy but also to heat and sound energy etc., indicating multiple energy - form transformations.

Answer:

D. Multiple transformations occur because the chemical energy of the fuel is changed to several forms of energy.
