What is the definition of meniscus in science?
Mercury does not wet glass – the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass. When liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop.
A meniscus is really a phase boundary that’s been curved due to surface tension. Within the situation water and many fluids, the meniscus is concave. Mercury creates a convex meniscus. A meniscus is exactly what occurs when you place a liquid right into a container. Whenever you put water inside a beaker or test tube, the thing is a curved surface. With many fluids, the attractive pressure between your liquid and also the container is more than the attraction between your individual liquid molecules. Next, do not know meniscus important? The meniscus plays an important role to maintain the soundness from the knee joint together with optimizing the tibiofemoral load transfer and distribution. This will help with preserving the healthiness of the articular cartilage. In this manner, how can you read a meniscus in chemistry? A meniscus occurs due to surface tension within the liquid and should be read at eye level. For any concave meniscus, the right volume is going to be read at the end from the curve. For any convex meniscus, the alternative holds true and also the correct studying is going to be towards the top of the bend.
Please Tell Me, How Do I Read a Meniscus Accurately? – For Chemistry students who may have questions about how to accurately read a meniscus during Chemistry practicals, this is arriving just in time.According to about.com,the meniscus isthe curve seen at the top of a liquid in.
Measure so that the line you are reading is even with the centre 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 centre of the meniscus.
The Different Meaning of the Term Meniscus in Science – There are different scientific definitions of the term meniscus, depending on whether you are referring to chemistry, physics, and biology or anatomy.
In anatomy and medicine, a meniscus is a crescent-shaped or semi-lunar structure that partially divides the cavity of a joint. A meniscus is a fibrocartilaginous tissue. Examples in humans are found in the wrist, knee, temporomandibular, and sternoclavicular joints. In contrast, an articular disk is a structure that completely divides a joint cavity.
The next time you pour some fluid into a tube, look at it from the side. You will see the liquid has a slight curve, either up or down. This curved surface, created by air pressure, is called a meniscus.
Sign up now (it’s free!) – The Greeks were built with a word for that lunar crescent, mniskos, which itself originated from the term for that moon, mn. Within the late 17th Century, the term meniscus was handed to similarly-curved lenses. Then in 1812, the curved surfaces of liquid were known with this word too. Later, the name seemed to be put on a crescent-formed cartilage in the knee, between your tibia and also the femur. These small, semi-lunar bits are essential for reducing friction during leg movement.

Meniscus in the body
A meniscus is a curve in the surface of a liquid, produced in response to the surface of the container or another object. It can be either concave or convex. A convex meniscus occurs when the molecules of the liquid repel the molecules of the container or object. This may be seen between mercury and glass in barometers. Conversely, a concave meniscus occurs when the molecules of the liquid attract those of the container. This can be seen between water and glass. Surface tension acts on concave menisci to pull the liquid up, and on convex menisci to pull the liquid down. This phenomenon is important in transpirational pull.
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. . . . Reading a meniscus properly is important for lab safety, since mixing incorrect amounts of materials can be dangerous.

Questions and Answers
An answer to the question: What is a meniscus?
Exactly what is a meniscus? A meniscus is exactly what occurs when you place a liquid right into a container. Whenever you put water inside a beaker or test tube, the thing is a curved surface. With many fluids, the attractive pressure between your liquid and also the container is more than the attraction between your individual liquid molecules. Therefore the liquid “sticks” aside from the container. Your teacher may have said you need to browse the test tube towards the “bottom” from the meniscus. So, you need to contain the tube up level together with your eye, and appear through it to determine the underside area of the meniscus. This requires a little practice, and you’ve got to estimate just a little. However if you simply always employ exactly the same method, and browse from the foot of the meniscus, you’ll have a constant method of doing the work. That can help reduce errors inside your experiments. A couple of fluids possess a “backwards” meniscus. A good example is mercury. Should you put mercury inside a test tube, it might be greater in the centre than in the edges.
Meniscus (liquid) Facts for Kids – Learn Meniscus (liquid) facts for kids.
A concave meniscus happens when the particles of the liquid are more strongly attracted to the container (adhesion) than to each other (cohesion). This causes the liquid to climb the sides of the container. This happens between water and glass. Water-based fluids like sap, honey, and milk also have a concave meniscus in glass or other wettable containers.

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. Instead, the top is curved inward, making it a little difficult to decide exactly where to read the volume. As pictured below, the volume should be read from the bottom of the meniscus. Why doesn’t water lie flat? Well, it has to do with the nature of the water molecules and glass molecules themselves. Water is made up of polar molecules, which have positively and negatively charged ends. Since opposites attract, the positive sides attract the negative sides, and all of the molecules stick to one another. This is why water droplets can form. Glass molecules also happen to be polar. Again, since polar molecules like to stick together, the water in a glass tube will actually tend to stick to the sides of the tube!

this is a concave meniscus, “are there any situations where might have “a convex meniscus?” Well sure, you can have a convex meniscus. If you were take that same glass beaker, instead of filling it with water if you filled it with say, mercury. If you filled it with mercury, you would get a meniscus.
How to Read a Meniscus in Chemistry Westlab
Liquids are difficult to measure with the naked eye due to surface tensions causing a meniscus to form on the circumference of the measuring object. In this article, you will learn what a meniscus is, why it forms and how you can accurately and precisely measure the volume of a liquid in laboratory graduated measuring (…)
Fluids take time and effort to determine using the human eye alone because of surface tensions creating a meniscus to create around the circumference from the calculating object. In the following paragraphs, become familiar with exactly what a meniscus is, why it forms and the best way to precisely and precisely measure the level of a liquid in laboratory graduated calculating glasses or plasticware.
A convex meniscus appears when molecules of liquid are strongly attracted to each other rather than to the wall of container. Most liquids, including water, show a concave meniscus but a great example of a convex meniscus is liquid mercury in a glass container. It is to be noted that in some cases, the meniscus appears in a straight line instead of any curvature at all. For example, water in some plastic cylinders. No meniscus makes measuring very easy.
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.

Adhesion is responsible for a meniscus and this has to do in part with water’s fairly high surface tension. 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. They’ll travel up the glass as far as water’s cohesive forces will allow them, until gravity prevents them from going further. Cohesion is an intermolecular attraction between like molecules (other water molecules in this case).
