The combustion of gasoline or diesel fuel
So that the engine doesnt freeze.
The generic name is "heat engine". Examples include combustion engines, such as the ones used in cars.
Cars use chemical energy in the form of thermal energy which is used to drive a piston crankshaft arrangement
Normally, friction between moving surfaces causes mechanical energy to convert to thermal energy (heat), as in the brakes of most cars.
Gasoline has chemical energy, that is easily converted to thermal energy and then to mechanical energy(movement), which is used to propel the car.
The wasted thermal energy in a car is primarily dissipated as heat through the exhaust system, radiator, and engine components. It is released into the surrounding environment, contributing to overall heat pollution. Some modern cars also utilize technologies like regenerative braking to recapture and convert a portion of this waste heat back into useful energy.
Fossil fuels
Hydrocarbon fuel.
Gasoline is a Mechanical energy because gasoline can make cars move and cars are moving things.
because cars create thermal energy. (basic GCSE science)
Ultimately the Sun. Cars run on fossil fuels which is made from the remains of organism that lived and grew on the planet in the past. These living organisms depended on sunlight as the source of their energy.
