What is a meniscus is and how it is used to measure liquids?
A meniscus is the curve of a liquid. Like when you are filling a glass of water, if you continue to put water in the glass after it has reached the top, then the extra water will go above the glass in a curved shape. When you are measuring liquids in for example a graduated cylinder, you would take the measurement from the bottom of the meniscus. I hope this helps!
When reading the volume of fluid in a graduated cylinder the eye should be?
When reading the volume of fluid in a graduated cylinder, the eye should be at the same level as the meniscus (the curve at the surface of the liquid). This helps to avoid parallax error and ensures an accurate reading of the volume.
Why do the sides go up on the beaker in meniscus?
Assuming that the liquid in the beaker is water.... Due to the structure of water (two hydrogen, one oxygen), it has a slight negative charge near the oxygen atom an a slightly positive charge near the hydrogen atoms. These slight charges allow the edges of the water to cling to the sides of the beaker, thus creating a meniscus. Some liquids, like mercury, actually would create a reversed meniscus (compare an alcohol thermometer with a mercury one).
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.
How many liquids are on the period table?
There are two liquids in periodic table. They are mercury and bromine.
Law of lower and upper meniscus levels in determining liquid solution?
In measuring liquids using graduated cylinder, there are two things to consider. 1.) CLEAR LIQUID and 2.) COLORED LIQUID (as we may say) In identifying the volume of CLEAR LIQUID (e.g. plain water, oil, alcohol, etc.), THE LOWER MENISCUS is read. For the COLORED LIQUID (e.g. soy sauce, ketchup, etc. ) the upper meniscus is get, since there is only one meniscus there.. (meaning there is no upper & lower meniscus.)
State two types of meniscus shape?
The two types of meniscus shape are concave and convex. Concave meniscus has a curved surface where the edges dip below the center, like in a test tube. Convex meniscus has a curved surface where the edges rise above the center, like in a droplet of water on a surface.

What two body parts have a meniscus?
The knee and the shoulder are two body parts that have a meniscus. The meniscus in the knee is a C-shaped piece of cartilage that acts as a cushion and helps with stability. In the shoulder, the meniscus is a fibrous structure that helps absorb shock and provide stability to the joint.
When reading the volume of fluid in a graduated cylinder the eye should be?
When reading the volume of fluid in a graduated cylinder, the eye should be at the same level as the meniscus (the curve at the surface of the liquid). This helps to avoid parallax error and ensures an accurate reading of the volume.
What is the bottom of the meniscus called?
The meniscus is located on the knee. It is made up of two different tissues that are known as cartilaginous tissues. One is on top, the other is on the bottom.
Is a mixture of two liquids heterogeneous or homogeneous?
No, it is not two liquids. It is two types of mixtures.
What causes a meniscus to form?
Everyone has two menisci (pl. of meniscus) in your knee joint. It helps to cushion the knee joint. It can occasionally get torn and because it has a very poor blood supply, it generally won't heal without surgery.
When two liquids are combined and they do not mix?
Your liquids are immiscible.
What are the two shapes of meniscus called?
The surface is concave if the liquid is attracted to the container walls and convex if it is not
How can be the two liquids become homogenous or hetero?
Two completely miscible liquids form a homegeneous solution.
When water is mixed with rubbing alcohol the two liquids completely dissolves. Are the two liquids miscible are they immiscible?
miscible
