Question

define angle of constant state any two characteristics of angle of contact​

Answer 1

Answer:

It has two characteristics: Angle of contact for a liquid in constant with a solid The angle of contact is constant for a given liquid-solid pair. If The angle of contact is large if the surface is not wet.

Additional information:-

Characteristics of the Angle of Contact:

The angle of contact is constant for a given liquid-solid pair. When the angle of contact between the liquid and a solid surface is small (acute), the liquid is said to wet the surface. ... If the angle of contact is large the surface is not wetted.

the angle between the meniscus and the containing walls of a column of liquid measured from the vertical wall below the surface of the liquid to the position of the tangent to the meniscus at its point of contact with the wall.
