Thermodynamic Cycles
Thermodynamic cycles are processes where a system, such as an engine, undergoes a series of changes in state, returning to its initial condition. These changes typically involve the conversion of heat energy into work, like in car engines or refrigerators. The cycle includes phases of heating, cooling, compression, and expansion. By continuously cycling through these phases, a system efficiently converts energy from one form to another, ultimately performing useful work while adhering to the laws of thermodynamics, which govern energy conservation and entropy.

Thermodynamic cycles are processes that describe how energy is converted and transferred in systems, typically involving heat and work. Think of it as a loop where a substance, often a gas, undergoes changes in temperature and pressure to perform work, like powering an engine. The cycle can consist of four main stages: heating, expanding, cooling, and compressing. This process repeats, allowing the system to efficiently convert heat energy into mechanical work. Common examples include the Carnot cycle and the Otto cycle, which are fundamental in understanding how engines and refrigerators operate.
