What causes a meniscus in science?
Why a meniscus occurs Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus.
How do you do a meniscus science?
If the meniscus is a concave meniscus, read at the lowest level of the curve. If the meniscus is convex, take your measurement at the highest point of the curve. The short answer: Take your measurement from the center of the meniscus.
What is an example of a meniscus?
The definition of a meniscus is the fibrous cartilage in a knee joint, or the curved upper surface of liquid that touches the sides of a jar, or a lens that is convex on one side and concave on the other. When oil is in a jar and the oil has a curve on the top of its surface, this is an example of meniscus.
What is meniscus in terms of physics?
The meniscus (plural: menisci, 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 concave or convex, depending on the liquid and the surface.
Is this what meniscus means in scientific terms?
A meniscus is the curved surface at the top of a column of liquid. In a science class, this liquid is usually water or some sort of aqueous solution, and the column is usually a graduated cylinder or a pipet. As you may have noticed, when water is in such a thin glass tube, it does not have a flat surface at the top.
What is the scientific definition of meniscus?
Medical Definition of meniscus. 1 : a crescent or crescent-shaped body. 2 : a fibrous cartilage within a joint: a : either of two crescent-shaped lamellae of fibrocartilage that border and partly cover the articulating surfaces of the tibia and femur at the knee : semilunar cartilage: (1)
How is a meniscus used in measuring?
A concave surface of a liquid resulting from surface tension. The bottom of the meniscus is used to measure the volume of a liquid in apparatus such as a graduated cylinder.
What do you measure in a meniscus?
Measure so that the line you are reading is even with the center of the meniscus . For water and most liquids, this is the bottom of the meniscus. For mercury, take the measurement from the top of the meniscus. In either case, you are measuring based on the center of the meniscus. For a flat meniscus, make sure the liquid is level. Oct 2 2019
