Froth flotation process for the concentration of ores is an illustration of the practical application of

$CH_4$ is adsorbed on $1 \ g$ charcoal at $0^{\circ} C$ following the Freundlich adsorption isotherm. $10.0 \ mL$ of $CH_4$ is adsorbed at $100 \ mm$ of $Hg$,whereas $15.0 \ mL$ is adsorbed at $200 \ mm$ of $Hg$. The volume of $CH_4$ adsorbed at $300 \ mm$ of $Hg$ is $10^x \ mL$. The value of $x$ is $....\times 10^{-2}$ (Nearest integer). [Use $\log_{10} 2=0.3010, \log_{10} 3=0.4771$]

Activated charcoal is used to remove colouring matter from pure substances. It works by
