What is the total kinetic energy of $0.6 \ mol$ of an ideal gas at a temperature of $27 \ ^oC$ in $J$?

Liquids diffuse more slowly than gases because.....

What is the temperature at which the kinetic energy of $0.3 \ mol$ of helium is equal to the kinetic energy of $0.4 \ mol$ of argon at $400 \ K$ (in $K$)?

$0.5 \text{ mole}$ 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

At $STP$,$0.5 \ mol$ of $H_2$ gas and $1 \ mol$ of $He$ gas:

$A$ bottle of dry ammonia and a bottle of dry hydrogen chloride connected through a long tube are opened simultaneously at both ends. The white ammonium chloride ring first formed will be:
