Why does a raincoat not get wet in the rain?

$A$ liquid does not wet the solid surface if the angle of contact is

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

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 ...... $^o$.

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:
