Engine thermodynamics. Animation showing the basic principles of thermodynamics in an engine. The transfer of heat energy from a hot chamber (red, left) to a cold chamber (blue, bottom) provides the power to drive a wheel (upper right). When the difference in energy is low, the wheel turns relatively slowly. Towards the end of the clip, the difference in energy is increased (symbolised by the raising of the hot chamber). This results in the wheel turning faster as more power is supplied by the engine.
