Why does physisorption decrease with the increase of temperature?

In the neutralisation of $KI$ by $AgNO_3$,the positive charge on the colloidal particles is due to the adsorption of:

Which of the following can adsorb the largest volume of hydrogen gas?

$10 \, mL$ of $1 \, mM$ surfactant solution forms a monolayer covering $0.24 \, cm^2$ on a polar substrate. If the polar head is approximated as a cube, what is its edge length?

The plot of $\log \frac{x}{m}$ ($y$-axis) and $\log p$ ($x$-axis) is a straight line inclined at an angle of $45^{\circ}$. When the intercept is $\log K = 0.3010$ (where $K = 2$) and pressure is $0.3 \ atm$,calculate the amount of solute in grams adsorbed per gram of adsorbent $\frac{x}{m}$ (given $\log 3 = 0.4771$ and $\log 0.3 = -0.5229$)?
