By adding soluble impurity in a liquid,the angle of contact

Consider a spherical body,one third of its volume is filled with a liquid which has a contact angle of zero with the surface of the sphere. If this sphere (along with the liquid) is taken to gravity-free space,then the shape of the liquid inside the sphere will look like:

The liquid meniscus in a capillary tube will be convex,if the angle of contact is

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:

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).

If a liquid does not wet the surface,its angle of contact is acute or obtuse?
