Can entropy change be zero for an irreversible process?

Click For Summary
SUMMARY

In the discussion regarding entropy change in irreversible processes, it is established that the entropy change for a closed system cannot be zero during an irreversible process. This conclusion is based on the second law of thermodynamics, which states that the total entropy of an isolated system can never decrease over time. The only scenario where entropy change can be zero is in a reversible process, which is not applicable to irreversible processes.

PREREQUISITES
  • Understanding of the second law of thermodynamics
  • Familiarity with the concepts of closed systems in thermodynamics
  • Knowledge of reversible and irreversible processes
  • Basic principles of entropy and its calculations
NEXT STEPS
  • Study the second law of thermodynamics in detail
  • Explore the differences between reversible and irreversible processes
  • Learn about entropy calculations in various thermodynamic systems
  • Investigate real-world examples of irreversible processes and their entropy changes
USEFUL FOR

Students of thermodynamics, physicists, and engineers interested in understanding the principles of entropy and its implications in closed systems and irreversible processes.
