Question

Fossil fuels are formed by the decomposition of dead plants and animals. Which flow chart describes the correct energy transformation when a car burns fossil fuels to accelerate? chemical energy → thermal energy → mechanical energy thermal energy → mechanical energy → chemical energy chemical energy → mechanical energy → thermal energy thermal energy → chemical energy → mechanical energy

Answer 1

The correct answer is(a) chemical energy → thermal energy → mechanical energy

Fossil fuels generate energy and the energy generated by them is in the form of chemical energy and by burning the fossil, the chemical energy is converted into thermal energy by combustion of fuel, this is now converted into mechanical energy when it was used for acceleration.

Answer 2

Answer: chemical energy- thermal energy- mechanical energy

Explanation:

Fossil fuels are the organic fuels produce by the activity of microbes living in the soil. These fossil fuels consist of elements which are the source of chemical energy. When these chemicals are burned they produce intense heat energy along with gases which exerts pressure over the machinery in the vehicle, which facilitates it's movement.

Therefore, chemical energy is converted into thermal energy and finally to mechanical energy.
