What are the angles of contact for wetting and non wetting liquids?

AI Generated Solution

To determine the angles of contact for wetting and non-wetting liquids, we can follow these steps: ### Step 1: Define Contact Angle The contact angle (θ) is the angle formed between the tangent to the liquid surface at the contact line and the solid surface. It is a measure of how well a liquid wets a solid surface. ### Step 2: Identify Wetting Liquids Wetting liquids are those that spread out on a surface. For these liquids, the contact angle is less than 90 degrees (θ < 90°). This means that the adhesive forces between the liquid and the solid surface are stronger than the cohesive forces within the liquid. ...

Angle of contact of a liquid with a solid depends on

Molecular forces exist between the molecules of a liquid in a container. The molecules on the surface have unequal force leading to a tension on the surface. If this is not compensated by a force, the equilibrium of the liquid will be a difficult task. This leads to an excess pressure on the surface. The nature of the meniscus can inform us of the direction of the excess pressure. The angle of contact of the liquid decided by the forces between the molecules, air and container can make the angle of contact. The direction of the excess pressure in the meniscus of a liquid of angle of contact 2pi//3 is
