What is the shape of the meniscus when a non-wetting liquid is placed in a capillary tube?

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

Why is Teflon coated on non-stick frying pans? Explain.

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:

$A$ hydrophilic surface is characterised by the contact angle at the water-solid interface. The value of the contact angle should be:

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:
