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

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

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

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

The value of the contact angle for kerosene with a solid surface is ........ $^o$.
