Dear student
1> Cottrell’s smoke precipitator, neutraliser the charge on unburnt carbon particles, coming out of chimney and they get precipitated and settle down at the floor of the chamber.

2> As physical adsorption, involves only weak vander woal’s force of interaction, so many layers of adsorbate get attached, while chemisorption involves chemical bond formation between adsorbate and adsorbent, so monolayer is formed.

We hope that clarifies your query.
