How do gasoline engines relate to chemistry
WebA combustion engine in a car is a thermal engine, as it uses gas and an electrical spark to produce a controlled explosion that generates energy and heat. The energy of the explosion is transformed into movement using the car's mechanical components. This movement of the car is what we call 'work'. WebJan 8, 2013 · The cars internal combustion engine converts the stored chemical energy of gasoline to motion and heat.
