Vehicles (cars, trucks, motorcycles, etc.) are machines that convert chemical energy (in fuels or in batteries) to the kinetic energy of the vehicle going down the road and to produce comforts such as cooled air (air conditioning) and producing wanted sounds (radio and recordings).

Question 10) Is your car able to convert all of the energy in the gasoline (or diesel, or battery, etc.) to doing what we want done (the car going down the road and possibly producing lights so that we can see at night, cold air to keep us comfortable, etc.)? (Hint: are heat, sound, or any other form of wasted energy formed by the car?) Give the evidence for your answer
