$A$ solid acts as an adsorbent because it has

Noble gases are adsorbed by

The mass of gas adsorbed,$x$,per unit mass of adsorbent,$m$,was measured at various pressures,$p$. $A$ graph between $\log(x/m)$ and $\log p$ gives a straight line with slope equal to $2$ and the intercept equal to $0.4771$. The value of $x/m$ at a pressure of $4 \text{ atm}$ is: (Given $\log 3 = 0.4771$)

Assuming Langmuir monolayer adsorption,the volume of nitrogen gas adsorbed on a sample of silica gel at $STP$ is $1.30 \, cm^3 \, g^{-1}$. The area occupied by a nitrogen molecule is $0.16 \, nm^2$. The surface area of silica gel per gram is ......... $m^2 \, g^{-1}$.

Assertion $(A)$: The property of adsorption is shown to a greater extent by solids than liquids.
Reason $(R)$: Solids like charcoal and silica can act as good adsorbents.

Which of the following statements is incorrect regarding physical adsorption?
