The total kinetic energy $(KE)$ of $1 \ mol$ of a monoatomic ideal gas at $27 \ ^oC$ is ........ $cal$.

$0.5 \text{ mole}$ of each of $H_{2}$,$SO_{2}$,and $CH_{4}$ are kept in a container. $A$ hole was made in the container. After $3 \text{ h}$,the order of partial pressures in the container will be

If a gas is expanded at constant temperature,which of the following is true?

According to the kinetic theory of gases,which of the following statements are correct?
$A$. Collisions are always elastic.
$B$. Heavier molecules transfer more momentum to the wall of the container.
$C$. Only a small number of molecules have very high velocity.
$D$. Between collisions,the molecules move in straight lines with constant velocities.
