Define angle of contact .

On what factors does the value of angle of contact depend ?

Explain angle of contact in the context of intermolecular forces.

Shape of menuscus of a liquid of zero angle of contact is

If a liquid does wet the surface ,its angle of contact is acute or obtuse ?

Liquid is stick to the glass then angle of contact for liquid glass will be obtain …..(acute /obtuse)

Liquid rises to a height of 2 cm in a capillary tube and the angle of contact between the solid and the liquid is zero. If the tube is depressed more now so that top of capillary is only 1 cm above the liquid, then the apparent angle of contact between the solid and the liquid is

The cohesive force between the molecules of liquid is more than the cohesive force between the molecules of plate then angle of contact obtain is …..(acute /obtuse) and free surface has shape ….. (concave/convex)

The cohesive force between the molecules of liquid is less than the cohesive force between the molecules of plate then angle of contact obtain is …. (acute /obtuse) and free surface has shape ….(concave/convex)

The angle of contact between mercury and glass is ……. Angle
