Work is done by the gas as it exerts a force through a distance, converting its energy into a variety of other forms—into the car’s kinetic or gravitational potential energy; into electrical energy to run the spark plugs, radio, and lights; and back into stored energy in the car’s battery.

It emphasizes the importance of heat in contexts like solar warmth, lava flows, and climate impacts of carbon dioxide. The potential of heat to perform work and convert into other energy forms, such as in car engines, is discussed, alongside the limitations in efficiency.
