Assertion: Each vibrational mode gives two degrees of freedom
Reason: By law of equipartition of energy, the energy for each degree of freedom in thermal equilibrium is
Reason: By law of equipartition of energy, the energy for each degree of freedom in thermal equilibrium is
View answer and explanation
Correct option: C
If Assertion is true and Reason is false
Option C is correct because each vibrational mode contributes two degrees of freedom (kinetic and potential energy), but the energy for each degree of freedom is , not .

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
