There are two principles you need to understand here called adhesion and cohesion. Adhesion is how much a substance sticks to another substance; cohesion is how much a substance sticks to itself.
Water's adhesive forces are stronger than its cohesive forces which cause it to stick to the walls of a container to create an downward meniscus.
What else can I help you with?
What bottom of the liquid line in a cylinder is called?
its called a meniscus
What is a meniscus why it necessary to know about it when measuring liquids?
The meniscus is the concave line of liquid that forms in a graduated cylinder (measuring volume) due to that liquid's adhesion (the tendency to want to stick to other things). When measuring a liquid's volume in a graduated cylinder, you read the volume from the bottom of the meniscus. Therefore, the meniscus does not measure anything, it is where you measure a liquid's volume from.
Uses of a graduated cylinder?
1. Look at the liquid at eye level 2. Measure from the meniscus (the curved line at the surface of the liquid) 3. Be sure to measure your intervals (the value of each measurement line on the cylinder)
What precautions to take when using measuring cylinder?
A measuring cylinder is used to measure the volume of liquids. A measuring cylinder is used for measuring solutions, liquids and also water. For example, a solution made up of salt and water could be measured.
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.
What is the curved line that forms when water is in a graduated cylinder?
This line is called the meniscus.
What is the the bottom of a curved line in a graduated cylinder?
The "bottom of a curved line" made by the liquid in a graduated cylinder could be called the "measuring line" or "reference line" in the application of that piece of labratory equipment. The curved surface of the liquid itself is called the meniscus, and we look to the bottom of the meniscus to make our reading as to the volume of the liquid in the graduated cylinder. The liquid in the cylinder "grabs" the sides of the cylinder and "pulls itself up" just a bit, and that creates the curve in the surface of the liquid. And that curve, the meniscus (which is from the Greek word for crescent), leaves us with a problem: where do we "read" the volume marked off by the graduations along the side of the cylinder? And the answer is, "At the bottom of the meniscus."
What is the fill line of a graduated cylinder called?
The fill line of a graduated cylinder is known as the meniscus. It is the curved surface of a liquid in the cylinder caused by the surface tension between the liquid and the glass. Scientists must take measurements at the bottom of the meniscus for accuracy.
What is the curved line at the surface of the liquid called?
Meniscus
Definition of curved line?
A kind of line which is not required to be straight. Curved lines are often called irregular lines.
What is the line on the graduated cylinder called?
meniscus
How do you use measuring cylinder?
A graduated cylinder is used to measure liquid volume in milliliters, mL. When you place a liquid into a glass graduated cylinder, you will see that the "line" at the top of the column of liquid is actually curved downward. This is called the meniscus. When you measure the liquid volume, you record the volume in mL at the bottom of the meniscus.

What is the meniscus line?
A meniscus line is the little line that you have at the top of a liquid. If you fill a glass up with water, the line that seems to sit at the top of the water that you see when you look at the glass at eye level is the meniscus line.
What can measure liquid?
A graduated cylinder, measuring cup, or beaker can be used to measure liquid volume accurately. It is important to use the correct measuring tool and ensure the meniscus (the curved surface of the liquid) is at the correct measurement line for accuracy.
Which is the most accurate way to read graduated cylinder?
at the bottom of the meniscus
