Question

At ordinary temperature the molecule remain in their
(A) Lowest vibrational level
(B) Highest vibrational level
(C) Can remain in any vibrational level
(D) Does not show any type of vibrations​

Answer 1

Answer:

B)

Explanation:

Vibrational energy involves additional degrees of freedom. Thus the degrees of freedom for a diatomic gas increases at higher temperatures.

Molar heat capacity is proportional to the number of degrees of freedom of the gas.

Thus the molar heat capacity also increases for a diatomic gas at higher temperatures.
