SUMMARY

The assertion that entropy remains unchanged in all adiabatic processes is incorrect. While adiabatic processes prevent heat transfer, they do not eliminate entropy generation due to irreversibilities within the system. Specifically, the entropy of a system does not change only in the case of adiabatic reversible processes. This distinction is crucial for understanding thermodynamic principles.

PREREQUISITES
  • Understanding of thermodynamic principles
  • Knowledge of adiabatic processes

For all adiabatic processes the entropy of the system does not change (speaking in general) Is this statement correct?
 
Science news on Phys.org
That statement is not correct. Entropy can be both transferred with heat and also generated by irreversibilities within the system. Adiabatic processes eliminate the first possibility.
 
In other words, the entropy of the system does not change for an adiabatic reversible process.
