Question

define angle of contact . on what factors does it depends ​

Answer 1

Answer:

hey mate here is your answer

Explanation:

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.

The angle of contact depends on the following factors: (a) The nature of liquid and solid. The nature of the liquid and the solid which is in contact to form the angle of contact. Contact Angle is constant for given liquid-solid pair. (b) The medium in which angle of contact is being made.

Hope it helps you.

Answer 2

Answer:

The angle of contact is the angle made by the tangent to the liquid surface at the point of contact with the solid surface inside the liquid.

The contact angle depends upon the medium above the free surface of the liquid, and the nature of the liquid and solid in contact.
