A liquid is filled in a spherical container of radius R up to a height h . At this position the liquid surface at the end is also horizontal. The contact angle is

(i) Water drops on two surfaces A and B has been shown in figure. Which surface is hydrophobic and which surface is hydrophilic? (ii) A liquid is filled in a spherical container of radius R till a height h. In this position the liquid surface at the edges is also horizontal. What is the contact angle between the liquid and the container wall?

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

A liquid is filled in a container to a height H. A small hole is opened in the side of the container a height h below the surface of the liquid. The distance L from the bottom of the container of the point where the stream of liquid leaving the container meets the ground is :

A liquid will not wet the surface of a solid if the angle of contact is
