It is from the Greek meaning crescent. When you measure the volume of water (or similar liquid) in a measuring cylinder, if you look carefully you will notice the surface water level is not perfectly flat. It will be curved, this is called the meniscus. To accurately measure the volume you must look at the meniscus at eye level and take the reading at the bottom of the meniscus.
The meniscus occurs because water is attracted to the glass/plastic. All equipment that is intended to measure volume will take into account the meniscus, as long as you take your reading with the meniscus at eye level. The measurement must be done at eye level in order to ensure no parallax error. NOTE Mercury's meniscus is convex rather than concave, as it is not attracted the glass/plastic.

∙ 11y agoThe meniscus (from the Greek for "crescent") is the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension.
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.

Both are cartilaginous tissues that provide structural integrity to the knee when it undergoes tension and torsion. The menisci are also known as "semi-lunar" cartilages — referring to their half-moon, crescent shape.

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.
What is the name of the bubble in the metric system?
The Meniscus is the name for bubble in the metric system
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.
When measuring you do the measurement from the bottom of the meniscus?
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.
What is the chemical definition of calcium hypochlorite?
The chemical definition of calcium hypochlorite is that it's a white crystalline compound used as a bleaching and disinfectant agent. The chemical formula is Ca(OCl)2.
What is the scientific definition of meniscus?
meniscus is the level of a liquid in a cylinder.
What has a flat meniscus?
A meniscus by definition isn't flat, but it has a curve instead, and the bottom of the curve is the actual volume of the liquid in the container.
Definition of curved line?
A kind of line which is not required to be straight. Curved lines are often called irregular lines.

What liquid's meniscus curve up?
Water's meniscus curves up. Mercury's meniscus curves down.
Does meniscus always concave?
Do you mean is a meniscus always concave? If so, then no. For example, the meniscus of mercury is convex.
