The reason we consider the surface area of the entire mass of Mercury, including the part of the surface that is in contact with the glass, is because mercury does not adhere at all to glass. So the surface tension of the mercury acts over its entire surface area, including where it is in contact with the glass. If instead of glass, the tube were made out of copper, the situation would be very different. Mercury aggressively adheres to copper. So in a copper tube, the level of mercury at the center of the tube will be lower rather than higher than at the edges

convex
Is a magnifying lens concave or convex in shape?
A magnifying lens is typically convex in shape.
Is a convex shape curves outwards?
Yes, a convex shape curves outward. In geometry, a shape is considered convex if, for any two points within the shape, the line segment connecting them lies entirely within the shape. This property ensures that a convex shape does not have any indentations or "inward" curves. Examples of convex shapes include circles, ellipses, and regular polygons.
Why is mercury surface convex?
Mercury's surface is convex due to its high surface tension, which is a result of the strong cohesive forces between its atoms. This property causes the liquid to minimize its surface area, leading to a shape that forms a convex meniscus in containers. Additionally, gravity plays a role in maintaining this shape, as the liquid's weight pushes down while surface tension pulls the molecules together, creating a stable, curved surface.
Is a parallelogram a square and a rhombus a convex shape?
A parallelogram need not be a square, it need not be a rhombus but it is a convex shape.
What is a convex heptagon?
No. Convex simply means that if you have a straight line segment joining any two points in (or on) a convex shape, then every point on that line segment in inside or on the shape. A convex shape can have 2 or more dimensions, it can by a polygon or have curved sides.
What is the shape of your eyelid?

What shape has all diagonals inside?
A convex shape.
How can you find a generalization for a triangle a parallelogram and a convex shape?
A parallelogram cannot be generalised to a convex shape with an odd number of sides.
Is a square is convex?
Yes, a square is a convex shape. In a convex shape, any line segment connecting two points within the shape lies entirely inside the shape. Since all interior angles of a square are right angles and all points within it satisfy this property, a square is considered convex.
