$A$ liquid does not wet the sides of a solid,if the angle of contact is

When the temperature is increased,the angle of contact of a liquid:

The angle of contact is $120^{\circ}$ when a cylindrical rod is vertically placed in a liquid. If the same rod is placed horizontally in the liquid, then the angle of contact is (in $^{\circ}$)

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:

Given below are two statements: One is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: Clothes containing oil or grease stains cannot be cleaned by water wash.
Reason $(R)$: Because the angle of contact between the oil/grease and water is obtuse.
In the light of the above statements,choose the correct answer from the options given below.

How does the angle of contact depend on temperature?
