Which best describes how energy changes form in a car's engine?
a single transformation occurs because the chemical energy of the fuel is changed to the mechanical energy of the car
a single transfomation occurs because the mechanical energy of the car originates from one spark
multiple transformations occur 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

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

Explanation:

In a car engine, multiple energy transformation takes place. The chemical energy storef in fuel is transformed into mechanical energy which helps move the wheels of the vehicle.

The mechanical energy can also be transformed into electrical energy through a sort of dynamo system in vehicles. Stereo players use the electrical energy to produce sound.

We see that multiple energy conversions are common in a motor car.
