A car engine is technically a heat engine that has no energy of its own but it converts the chemical energy in the fuels into heat and then into kinetic energy by turning a rotating shaft.
The chemicals that react to make the engine work consists of carbon and hydrogen from the gasoline in the fuel tank, and oxygen taken from the atmosphere. The carbon reacts with oxygen to produce carbon dioxide and heat, while the hydrogen reacts with oxygen to produce water and heat.

How is energy conserved when a car is going down a hill with no brakes?
The engine doesn't have to use as much fuel when the car is traveling downhill.
What is a energy transformation in a car engine?
The chemical energy is transformed in kinetic energy.
What energy form does a car engine transform from chemical energy?
Chemical energy transforms to kinetic energy which makes the car move.
How is energy dissipated from a car engine?
Heat
What form of energy is generated when gasoline is burned in a car engine and the car moves?
kinetic energy is created
When gasoline is burned in a car engine what energy is converted into another energy?
Chemical Energy into Mechanical Energy
What is the wasted energy from a car engine?
heat and sound
How is electrical energy use in car?
It starts the engine
What kind of energy in car engine?
Chemical energy is being converted to thermal energy which is then converted to mechanical energy and finally to kinetic energy which moves the car. Kinetic energy is then converted to thermal energy in the brakes to stop the car.
When gasoline is burned in a car engine and the car moveswhat energy is generated?
The chemical energy (the fuel) turns into kinetic energy (the car moving) and heat energy(given off by burning fuel).
What energy changes take place in a car engine?
chemical
Why does adding oil increases efficiency?
The purpose of adding oil to a car i to lubricate the engine. if the engine is not lubricated there will be much more friction between gears and friction generates heat. because energy is needed to create heat that energy is taken away from the energy that would be propelling the car forward. this causes the efficiency yo drop.
