Question

Assirtion Degree of freedom of a monjoatomic gas is always three, whether we concider vubrationaol effects or not.
Reason At all temperatures (low or high), vibrational kinetic energy of an ideal gas is zero
A. If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
B. If both Assertion and Reason are correct but Reason is not the correct explation os Assertion.
C. If Assertionis true bur Reason is false.
D. If Assertion is false but Reason is true.

Answer 1

Correct Answer - C
In ideal gases, there is no inter-partical interaction. If the gas is monoatomic so no vibrational energy is there. `therefore` Only the kinetic energy contribute to the internal energy.
