Heat addition in carnot cycle
Web3. The Carnot Cycle. A Carnot cycle is shown in Figure 3.4. It has four processes. There are two adiabatic reversible legs and two isothermal reversible legs. We can construct a Carnot cycle with many different … Web16 de ene. de 2024 · For the Carnot cycle isothermal expansion the heat source (thermal reservoir) temperature is infinitesimally greater than the gas temperature in order for heat transfer to be possible. Then the ideal gas does an infinitesimal of work equal to the infinitesimal amount of heat transferred in, thereby keeping the gas temperature constant.
