Write the important physical properties of liquids.

At constant volume and temperature conditions,the rate of diffusion $D_A$ and $D_B$ of gases $A$ and $B$ having densities $\rho_A$ and $\rho_B$ are related by the expression:

Which gas volume is measured in a sample by using a solution of $CuCl$ in $NH_4OH$ through the measurement of volume change?

When $0.0168 \ mol$ of $O_2$ obtained from the decomposition of $KClO_3$ is collected over water at $25 \ ^oC$,the volume is $428 \ mL$ and the total pressure is $754 \ mm$. What is the aqueous tension (water vapor pressure) at $25 \ ^oC$ in $mm$?

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

Sulphur dioxide $(SO_2)$ and oxygen $(O_2)$ were allowed to diffuse through a porous partition. $20 \ dm^3$ of $SO_2$ diffuses through the porous partition in $60 \ seconds$. The volume of $O_2$ in $dm^3$ which diffuses under the similar conditions in $30 \ seconds$ will be (atomic mass of sulphur $= 32 \ u$)
