Which factors can cause a change in the physical states of matter?

To which of the following gaseous mixtures is Dalton's law of partial pressures not applicable?

For the diffusion of a gas at pressure $P$,the rate of diffusion is expressed by :

Fill in the blanks:
$(1)$ The forces of attraction and repulsion between molecules and atoms are called ....... .
$(2)$ The attractive intermolecular forces between molecules of a substance are also known as .............. .
$(3)$ London forces are also known by the name of ........... .
$(4)$ The mathematical form of Charles's Law is ........ .

At the same temperature and pressure,the rate of diffusion of gas $X$ is $3 \sqrt{3}$ times that of a gaseous hydrocarbon of molar mass $54 \ g \ mol^{-1}$. The molar mass of $X$ in $g \ mol^{-1}$ is
