SUMMARY

The Carnot Cycle is a theoretical thermodynamic cycle that operates under the principle of reversible processes. In this cycle, heat exchange occurs in an infinitesimally slow manner, allowing the heating process to be reversible. This contrasts with typical heat exchanges, which are irreversible unless conducted under quasi-static conditions. The key takeaway is that the reversibility of heating in the Carnot Cycle is due to its adherence to quasi-static processes.

Hi,

I am thinking about the Carnot-Cycle-Process.
I know that a heat exchange is always irreversible.

But in the Carnot-Cycle, there is heating too.
Why is that kind of heating, in the Carnot-Process reversible?

Thx Abby

Heat exchange is always irreversible only for the processes which are not infinitesimally slow (or quasi-static or quasi-equilibruum) processes.

In Carnot-Cycle heating is done infinitesimally slowly, that's why it is reversible.
