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

Why does a raincoat not get wet in the rain?

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

For which of the two pairs,the angle of contact is the same?

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:

What is the nature of the meniscus for a liquid with an angle of contact of $0^{\circ}$?
