If the average kinetic energy $(K.E.)$ of $CO_2$ at $27\,^oC$ is $E$,what is the average kinetic energy of $N_2$ at the same temperature?

Which of the following statements is not correct regarding the kinetic theory of gases?

The mass of molecule $A$ is half the mass of molecule $B$. The $rms$ speed of $A$ is twice the $rms$ speed of $B$. If two samples of $A$ and $B$ contain the same number of molecules and are taken in two separate containers of equal volume,what will be the ratio of the pressure of $A$ to the pressure of $B$ $(P_A/P_B)$?

What happens to the pressure if the collisions of gas molecules are not elastic?

Which of the following gases has the largest mean free path?

For one mole of a monoatomic gas with molar mass $M$,the root mean square velocity is $u_{rms}$. What is the relationship between $u_{rms}$ and the average kinetic energy $E$?
