Assertion: Vibrational energy of diatomic molecule corresponding to each degree of freedom is .
Reason: For every molecule, vibrational degree of freedom is 2.
Reason: For every molecule, vibrational degree of freedom is 2.
View answer and explanation
Correct option: C
If assertion is true, but reason is false
The assertion is true, but the reason is false (Option C). Vibrational energy is kT, but diatomic molecules have 2 vibrational degrees of freedom (KE and PE).

Assertion: The pressure exerted by an enclosed ideal gas does not depend on the shape of the container.
Reason: The pressure of an ideal gas depends on the number moles, temperature and volume of the enclosed If is the velocity of sound in air and is the rms velocity, then Four particles have velocities . The root mean square of the particles is (in ) The translational degrees of freedom and rotational degrees of freedom of molecule are: On any planet, the presence of atmosphere implies (= root mean square velocity of molecules and escape velocity) At a given temperature, the pressure of an ideal gas of density is proportional to
