Thermodynamic cycle

A thermodynamic cycle is a series of processes that a system undergoes, returning to its initial state, often used in engines and refrigerators. Think of it as a continuous path where energy is transformed—like taking in fuel, converting it to work, and expelling waste. Common examples include the Carnot cycle and the Otto cycle in car engines. These cycles reveal how energy flows and changes forms while maintaining the principles of thermodynamics, which govern heat, work, and energy conservation. Understanding these cycles is essential in designing efficient machines and optimizing energy use.
