WebWe know that internal energy is a state variable, which means the internal energy at point A will always be the same regardless of the path that leads to point A. Therefore, there is no change in internal energy when a Carnot cycle is completed, because we started at point A and finished at point A. WebThe Carnot cycle consists of the following four processes: A reversible isothermal gas expansion process. In this process, the ideal gas in the system absorbs qi n amount heat from a heat source at a high temperature Th, expands and does work on surroundings. A reversible adiabatic gas expansion process.
