Write the important physical properties of liquids.

In a mixture of $CO_2$ and $CH_4$ in a closed vessel at a constant temperature,the total pressure is $8.3 \times 10^4 \, Pa$. If the partial pressure of $CO_2$ is $2.8 \times 10^4 \, Pa$,what will be the partial pressure of $CH_4$?

$3.2 \ g$ of oxygen is diffused in $10 \ min$. Under similar conditions,$2.8 \ g$ of nitrogen will diffuse in .............. $min$.

The units of surface tension and viscosity of liquids respectively are

Isochores are drawn at

$X \ mL$ of $H_2$ gas effuse through a hole in a container in $5 \ seconds$. The time taken for the effusion of the same volume of the gas specified below under identical conditions is
