Show With The Help Of Diagrams How A Liquid Surface Meets A Solid When The Angle Of Contact Is (i) Smaller Than 90 Degree, (ii) Greater Than 90 Degree.
To find whether the angle of contact between a solid and a liquid is obtuse or acute, let us consider the case of a solid, liquid and air in contact.…

What Is The Shape Of A liquid Drop On A Horizontal Plate?
When a liquid drop is placed on a horizontal plate, there are two forces acting on that drop of the liquid, the force due to surface tension, the force due…
