Assertion: The ratio for a monatomic gas is less than for a diatomic gas.
Reason: The molecules of a monatomic gas have more degrees of freedom than those of a diatomic gas.
Reason: The molecules of a monatomic gas have more degrees of freedom than those of a diatomic gas.
View answer and explanation
Correct option: C
If Assertion is true but Reason is false
Option C (Assertion is true but Reason is false) is correct because the ratio of specific heats is indeed lower for monatomic gases, but this is because monatomic gases have *fewer* degrees of freedom.
