The viscosity of the solvent depends on

Intermolecular forces and thermal energy decide the physical state of matter. Explain.

If a gas diffuses $1/5$ times as fast as hydrogen,its molar mass will be....

The $\%$ composition by volume of $Cl_2, H_2$,and $N_2$ are in $1:2:7$ by proportion. If the total pressure is $40 \ bar$,find the partial pressures of each gas?
[ Partial pressure $= \frac{\text{Volume } \% \times \text{Total pressure}}{100} ]$

The interaction energy of $London$ forces between two particles is proportional to $r^{x}$,where $r$ is the distance between the particles. The value of $x$ is:

If the rate of diffusion of $A$ is $5$ times the rate of diffusion of $B$,what will be the ratio of the densities of $A$ and $B$?
