Let denote the root mean square speed of the molecules in an ideal diatomic gas at absolute temperature . The mass of a molecule is ' '. Neglecting vibrational energy terms, which is false?
View answer and explanation
Correct option: C
The average rotational kinetic energy of a molecule is
Option D is correct because in an elastic collision the relative velocity is unchanged in magnitude but gets reversed in direction.

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
