Assertion : Vibrational energy of particle at temperature T is kT.
Reason : For every particle, vibrational degree of freedom is 2.
Reason : For every particle, vibrational degree of freedom is 2.
View answer and explanation
Correct option: D
If both Assertion & Reason are False
Option D is correct because the vibrational energy of a particle at temperature T is not simply kT, and a particle can have more or less than 2 vibrational degrees of freedom depending on the molecular structure.

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
