Which shape does a liquid have in its lowest energy state?

If $X \, mL$ of $H_2$ gas diffuses through a hole in a container in $5 \, s$,what is the time taken for the diffusion of the same volume of another gas under identical conditions?

Write the order of kinetic energy for solid,liquid,and gas.

$A$ mixture of $N_2$ and $Ar$ gases in a cylinder contains $7 \ g$ of $N_2$ and $8 \ g$ of $Ar$. If the total pressure of the mixture of gases in the cylinder is $27 \ bar$,the partial pressure of $N_2$ is $......... \ bar$.
[Use atomic masses (in $g \ mol^{-1}$) : $N=14, Ar=40$]

The rate of diffusion of a gas is ..... times that of hydrogen. (Molecular weight = $98$)

Why are liquids and gases categorised as fluids?
