Sure : water is the prime example. It's all about surface tension.

Does meniscus always concave?
Do you mean is a meniscus always concave? If so, then no. For example, the meniscus of mercury is convex.
Why does a meniscus occur?
It is because of the surface tension and cohesian of the molecules. It can be concave or convex.
How does adhesion and cohesion results to the formation of a meniscus?
if adhesion>cohesion, concave meniscus from out if ahesion<cohesion, convex if adhesion=cohesion, flat surface
When does the meniscus of a liquid in a glass tube curve downward?
A meniscus is caused by surface tension and It curves down (concave) when the liquid adheres to the container more than to itself, like water and glass. Mercury clings more to itself than glass, so it is curved up (convex)
What is the difference property between convex and concave glass?
Convex lens converges the light and a concave lens diverges the light..
Does meniscus always concave?

Why does mercury have convex meniscus?
Mercury has a convex meniscus because the intermolecular forces between mercury atoms are stronger than those between mercury atoms and glass molecules of a tube. The outermost mercury atoms are attracted to central mercury atoms and go towards the center of the tube. This force of attraction is slightly stronger than the force of gravity on the uppermost mercury molecules, so the meniscus is slightly elevated to a peak and is convex.
Every thing about Mercury?
Mercury is a poisonous liquid with a shiny surface and a convex meniscus, especially at room temperature.
What kind of characteristics does mercury have?
At room temperature, a clean sample is a shiny liquid with a convex meniscus.
State two types of meniscus shape?
Convex and concave or else they are also known as the upper meniscus and the lower meniscus
Would a graduated cylinder be read at the middle of a meniscus?
The answer depends on the liquid, or more specifically, how the surface tension in the liquid affects the meniscus. It should be the top of the meniscus for liquids such as mercury but the bottom for liquids such as water or alcohol.
Why is mercury curved upward?
The meniscus (plural: menisci, from the Greek for "crescent") is the curve in the upper surface of a liquid to the surface of the container or another object. It can be either convex or concave. A convex meniscus occurs when the molecules have a stronger attraction to each other (cohesion) than to the material of the container (adhesion). This may be seen between mercury and glass in barometers and thermometers. Conversely, a concave meniscus occurs when the molecules of the liquid attract those of the container's, causing the surface of the liquid to cave downwards. This can be seen in a glass of water. One can over-fill a glass with mercury and produce a convex meniscus that rises above the top of the glass, due to the vacuum created with the airtight substance.
What is a curved surface on a liquid called?
A meniscus, but whether it has a positive curve or a negative one depends on whether it wets the glass.
Is the curve at a liquids surface by which you measure the volume of a liquid?
The meniscus is the curve at a liquid's surface by which one measures the volume of the liquid. A meniscus can be concave or convex depending on whether it is attracted to itself or the glass.
How is a meniscus used in measuring?
As the diameter of the container decreases, the meniscus becomes more pronounced. The meniscus may be convex (curving upward) or concave (curving downward). Most of the time you will find that the meniscus is concave. The most notable exception is the meniscus that forms from mercury. When taking measurement readings it is important that the reading is done properly. The following rules must be adhered to: I. Read the meniscus at eye level. Do not read the meniscus from above or below eye level. Significant measurement errors may occur II. Read the bottom of a concave meniscus and the top of a convex meniscus.

How does adhesion and cohesion results to the formation of a meniscus?
