Question

The purpose of a car engine is to transform the chemical energy of gasoline into kinetic energy of the car in motion. Gasoline is burned in the engine to create that movement. However, gasoline engines are typically only about 20% efficient. What happens to the rest of the energy released from the burning gasoline?

Answer 1

heat

Step-by-step explanation:

most of the gasoline's energy is released as heat energy rather than kinetic energy on the pistons. this is why a car engine must constantly be cooled by the water to air heat exchanger we call a radiator
