Which outcome results when heat is added to an engine undergoing an irreversible thermodynamic cycle stage?

💡 Explanation

When heat is added during an irreversible stage, entropy generation occurs within the system because the process isn't quasi-static, therefore the entropy increase is greater than the heat added divided by the temperature. That causes entropy increase, rather than isothermal expansion, reversible conversion, or entropy decrease due to irreversibility effects.
