Vedclass · Answer

(A) Cohesive force is the force of attraction between molecules of the same substance. This force is responsible for the surface tension of liquids,which causes liquid drops to take a spherical shape to minimize surface area. Thus,$(a)$ matches with $(iii)$.Adhesive force is the force of attraction between molecules of different substances. When writing with chalk on a blackboard,the chalk particles stick to the board due to adhesive forces. Thus,$(b)$ matches with $(i)$.Therefore,the correct matching is $(a-iii), (b-i)$.

Column-$I$	Column-$II$
$(a)$ Cohesive force	$(i)$ Useful for writing by chalk on blackboard.
$(b)$ Adhesive force	$(ii)$ Useful in soldering.
	$(iii)$ Useful for formation of spherical drops of liquid.

Force in Column-$I$ and its use in Column-$II$ are given. Match them appropriately.
