What is the order of intermolecular forces in solids,liquids,and gases?

What is the ratio of kinetic energy of $7 \ g$ of nitrogen and $4 \ g$ of oxygen at $T \ K$?

If $N_2, O_2, H_2$,and $He$ gases are filled separately in four car tubes at the same pressure,which gas will diffuse first?

$12 \ cm^3$ of $SO_{2(g)}$ diffused through a porous membrane in $1 \ minute$. Under similar conditions $120 \ cm^3$ of another gas diffused in $5 \ minutes$. The molar mass of the gas in $g \ mol^{-1}$ is

$A$ container consists of a mixture of four gases: $5 \text{ g } H_2$,$8 \text{ g } He$,$50 \text{ g } CO_2$,and $20 \text{ g } Ne$ at a certain temperature. Which of the following gases exerts the minimum partial pressure?

In which of the following gas mixtures does Dalton's Law of Partial Pressure not apply? Why?
$(i)$ $CO_2 + O_2 + N_2$
$(ii)$ $CO + O_2$
$(iii)$ $NH_3 + HCl$
$(iv)$ $HCl + O_2$
