Adsorption is multilayer in the case of

If the initial pressure of a gas is $0.03 \, atm$,the mass of the gas adsorbed per gram of the adsorbent is $...... \, \times 10^{-2} \, g$. Based on the provided graph,determine the value.

Select the graph that correctly describes the adsorption isotherms at two temperatures $T_{1}$ and $T_{2}$ $\left(T_{1}>T_{2}\right)$ for a gas :
($x-$ mass of the gas adsorbed ; $m-$ mass of adsorbent ; $P -$ pressure)

The correct order of the volume of $NH_3, CO_2$,and $H_2$ gases adsorbed on $1 \ g$ of charcoal at $300 \ K$ is:

Which forms multimolecular layers during adsorption?

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: In expensive scientific instruments,silica gel is kept in watch-glasses or in semipermeable membrane bags.
Reason $(R)$: Silica gel adsorbs moisture from air via adsorption,thus protects the instrument from water corrosion (rusting) and/or prevents malfunctioning.
In the light of the above statements,choose the correct answer from the options given below:
