Question 6: Thermodynamics & KTG

Question

Assertion : Vibrational degree of freedom of
a di-atomic gas molecule appears at every
high temperature.
Reason : Di-atomic gas has two vibrational
degree of freedom in one direction.

Accepted Answer

There are two vibrational degree of freedom of
di-atomic gas molecules at high temperature.
Hence, vibrational degree of freedom of a di-atomic
gas molecule appears at every high temperature
because vibration in gas molecules is directly
proportional to the square root of its temperature.
Hence, both assertion and reason are true but
reason is not the correct explanation of assertion.

Answer

If both assertion and reason are true and reason is the correct explanation of assertion.

Answer

If both assertion and reason are true, but reason is not the correct explanation of assertion.

Answer
