AIIMS 2014 Physics Thermodynamics MCQ Question
Assertion Thermodynamic process in nature are irreversible. Reason Dissipative effects cannot be eliminated.
If both the assertion and reason are true and reason explains the assertion.
If both the assertion and reason are true but reason does not explain the assertion.
If assertion is true but reason false
If assertion is false but reason is true
Correct Answer
Detailed Explanation
The assertion is true because all natural thermodynamic processes are indeed irreversible, as they tend to increase the overall entropy of the system. However, the reason is false; while dissipative effects are present in real processes, they can be theoretically eliminated in idealized scenarios (e.g., in reversible processes). Thus, the correct answer is C: the assertion is true, but the reason is false.
