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

$A$ liquid wets a solid completely. The meniscus of the liquid in a sufficiently long tube is

If $S_1, S_2$ and $S_3$ are the tensions at the liquid-air,solid-air,and solid-liquid interfaces respectively,and $\theta$ is the angle of contact at the solid-liquid interface,then:

$A$ capillary tube is dipped vertically in a liquid. If the liquid surface is hemispherical,then the angle of contact $\theta$ is

Why does a raincoat not get wet in the rain?

Explain the angle of contact in the context of intermolecular forces.
