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

$A$ gaseous mixture was prepared by taking equal moles of $CO$ and $N_2$. If the total pressure of the mixture was found to be $1 \ atm$,the partial pressure of the nitrogen $(N_2)$ in the mixture is ............ $atm$.

If $P_1$ is the partial pressure of a gas and $x_1$ is its mole fraction in a mixture,then the correct relation between $P_1$ and $x_1$ is:

Which of the following gas mixtures will not obey Dalton's law of partial pressure?

Which of the following gases is not easily soluble in water?

$A$ gaseous mixture of $2$ moles of $A$, $3$ moles of $B$, $5$ moles of $C$, and $10$ moles of $D$ is contained in a vessel. Assuming that gases are ideal and the partial pressure of $C$ is $1.5 \ atm$, what is the total pressure (in $atm$)?
