$A$ glass plate is partly dipped vertically in mercury and the angle of contact is measured. If the plate is inclined,then the angle of contact will

Why does a raincoat not get wet in the rain?

If a capillary tube is dipped into a liquid and the levels of the liquid inside and outside are the same,then the angle of contact is ...... $^o$.

Fill in the blanks:
$(i)$ If a liquid sticks to the glass,the angle of contact for the liquid-glass interface will be ....... (acute / obtuse).
$(ii)$ The angle of contact between mercury and glass is .......... (acute / obtuse).

Given below are two statements:
Statement-$I$: When a capillary tube is dipped into a liquid,the liquid neither rises nor falls in the capillary. The contact angle may be $0^{\circ}$.
Statement-$II$: The contact angle between a solid and a liquid is a property of the material of the solid and liquid as well.
In the light of the above statements,choose the correct answer from the options given below.

Two liquids $A$ and $B$ have $\theta_{A}$ and $\theta_{B}$ as contact angles in a capillary tube. If $K = \cos \theta_{A} / \cos \theta_{B}$,then identify the correct statement:
