Energy can be changed from one form to another. changes in the form of energy are called energy conversions. in an automobile engine, fuel is burned to convert into heat energy. the is then changed into . identify the correct order of energy conversion in an automobile engine. a) heat → chemical → mechanical b) chemical → mechanical → heat c) mechanical → heat → chemical d) chemical → heat → mechanical

The correct answer is D) chemical → heat → mechanical.

According to the law of conservation of energy, energy cannot be created or destroyed in an isolated system, but it can only change the form.

The correct order of energy conversion in an automobile engine is given below:

In an automobile engine, fuel is burned to convert chemical energy into heat energy. The heat energy is then changed into mechanical energy.  

chemical → heat → mechanical is correct.

why ?

because : Gas (chemical) is combusted to make heat energy which pushes the pistons to produce mechanical energy.
