A vessel contains a mixture of one mole of oxygen and two moles of nitrogen at 300 K. The ratio of the average rotational kinetic energy per molecule to that per molecule is
View answer and explanation
Correct option: A
0.042361111
Option A (01:01) is correct because the average rotational kinetic energy depends only on temperature and degrees of freedom, which are the same for both gases.

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
