Which sequence describes the energy conversions in a car's engine? a) chemical to thermal to mechanical b) mechanical to thermal to chemical c) thermal to mechanical to chemical d) kinetic to potential to mechanical

The correct sequence of the energy conversion in a car's engine is A) chemical to thermal to mechanical.

EXPLANATION:

A car has a internal combustion engine. The function of the internal combustion engine is that it converts the stored chemical energy in fuels like petrol or diesel into thermal energy.

The thermal energy produced by the combustion engine will be transformed into mechanical energy. The mechanical energy will perform work on the piston for which the vehicle will be accelerated.

Hence, the correct order will be chemical to thermal to mechanical.

what is the actual question though?
