How is a meniscus used to measure volume?
A meniscus occurs because of surface tension in the liquid and must be read at eye level. For a concave meniscus, the correct volume will be read at the bottom of the curve. For a convex meniscus, the opposite is true and the correct reading will be at the top of the curve.
How do you read the volume measurement using graduated cylinder?
Reading a Graduated Cylinder Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.
What is a meniscus on a graduated cylinder?
When a liquid is placed into a graduated cylinder, the surface takes on a curved shape. This curve is known as a meniscus. The graduated cylinder is calibrated so that reading the bottom of the meniscus, when viewed at eye level, will give accurate results.
Why do you measure from the meniscus?
The location of the mark on the glass is where the bottom of the meniscus should be in order to have the "true" volume be what's marked. So by measuring from the bottom of the meniscus, you're synchronizing your measurement procedure with the procedure of the people who originally calibrated the markings on the glass.
What is meniscus in measuring cylinder?
The Meniscus 1. When observing a volume of a liquid in a graduated cylinder, graduated pipette, or buret, read the point on the graduated scale that coincides with the bottom of the curved surface of the liquid. The curved surface of the liquid is called the meniscus.
What is meniscus in water?
What is a meniscus? A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.
What is a meniscus and how is it used?
The meniscus is a c-shaped pad of cartilage in the knee that acts as a shock absorber. Each knee has two menisci. Meniscus tears are common knee injuries. Knee arthroscopy is often used to treat meniscal tears.
What is meniscus used for?
meniscus definition. 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.
How do you read a meniscus sample?
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.
When reading a graduated cylinder should you read the meniscus?
The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.
What is the meniscus?
The meniscus is a C-shaped piece of tough, rubbery cartilage that acts as a shock absorber between the shinbone and the thighbone. It can be torn if you suddenly twist your knee while bearing weight on it. A torn meniscus is one of the most common knee injuries.

What is meniscus in terms of the graduated cylinder?
Biology Glossary search by EverythingBio.com. 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.
Where do you read the meniscus inside a graduated cylinder quizlet?
The meniscus must be read consistently from the top of the graduated cylinder.
What is a meniscus and how do you use it to accurately measure liquids?
What is a meniscus and how do you use it to accurately measure liquids? the curve of the upper surface of a liquid when it is placed in a column; used to accurately measure liquids by reading the bottom of it.
Why is the meniscus important?
The meniscus plays a vital role in maintaining the stability of the knee joint along with optimizing the tibiofemoral load transfer and distribution. This also helps in preserving the health of the articular cartilage.
What is the use of meniscus?
Function. The menisci act to disperse the weight of the body and reduce friction during movement. Since the condyles of the femur and tibia meet at one point (which changes during flexion and extension), the menisci spread the load of the body's weight.
What is a meniscus reading?
The meniscus of most liquids used in volumetric calibrations is concave-up, with the lowest point in the center that is used to determine the meniscus reading. The curvature of a meniscus is related to the surface tension of the liquid and inversely related to the diameter of the tubing in which it is formed.
What is the meniscus in a graduated cylinder quizlet?
– A meniscus is the curvature of the upper surface of a liquid in glassware due to tension forces acting between the glass and the liquid.
What is a meniscus and how do you use it to accurately measure liquids quizlet?
What is a meniscus and how do you use it to accurately measure liquids? the curve of the upper surface of a liquid when it is placed in a column; used to accurately measure liquids by reading the bottom of it.
How does the meniscus work?
Two pieces of cartilage sit inside your knee, between your thighbone (femur) and shinbone (tibia). This cartilage is the meniscus. The rubbery wedges of cartilage act like shock absorbers for your knee, providing cushioning for your bones and knee joint.
What is meniscus in cylinder?
When a liquid is placed into a graduated cylinder, the surface takes on a curved shape. This curve is known as a meniscus. The graduated cylinder is calibrated so that reading the bottom of the meniscus, when viewed at eye level, will give accurate results.
How do you read a meniscus in chemistry?
The key to getting an accurate reading, is to measure the center of the meniscus whether it be concave or convex. E.g. with a concave meniscus, measure the bottom of the meniscus and for convex meniscus, take the reading from the top of the meniscus.
How should you read the volume of water using a volume measuring device with meniscus?
How should you measure the volume of a liquid? put glass on flat surface, pour the liquid in GC , read the value on the graduated cylinder from the bottom of the meniscus at eye level.
What is the importance of the meniscus?
The meniscus plays a vital role in maintaining the stability of the knee joint along with optimizing the tibiofemoral load transfer and distribution. This also helps in preserving the health of the articular cartilage.
Why is there a meniscus in a graduated cylinder?
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.
What is the meniscus used for?
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.
