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.
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.
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)
2d images for measuring cylinder?
To calculate the volume of a liquid in a measuring cylinder from a 2D image, you would need to know the dimensions of the cylinder and use the height of the liquid to estimate the volume by multiplying the cross-sectional area of the cylinder by the height of the liquid. Another way could be to use image analysis software to analyze the image and estimate the volume based on known parameters.
Why should you measure a liquid at the bottom of the meniscus?
The liquid molecules are more strongly attracted to the graduated cylinder than to each other. This causes the liquid to rise up on the sides of the graduated cylinder. Therefore it is important to read the line, even with the center of the meniscus, and at the bottom of the meniscus to accurately measure the volume of a liquid in the graduated cylinder. If you are still a bit confused I also found some information at this website: http://chemistry.about.com/od/chemistrylabexperiments/qt/meniscus.htm
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.
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 curved line that a liquid creates when it is placed into a gratuated cylinder is the?
The curved line that a liquid creates in a graduated cylinder is called the meniscus. This curvature occurs due to surface tension and the adhesive forces between the liquid and the walls of the cylinder. In most cases, the meniscus is concave, meaning it dips downward at the edges, and it is important to read the measurement at the bottom of the meniscus for accuracy.
What is the curved line on a graduated cylendar?
The curved line on a graduated cylinder, known as the meniscus, occurs due to the surface tension of the liquid and the adhesive forces between the liquid and the walls of the cylinder. When measuring the volume of a liquid, you should read the measurement at the bottom of the meniscus to ensure accuracy. This is particularly important for precise measurements in scientific experiments.
Why are there lines on a graduated cylinder?

Which is the most accurate way to read graduated cylinder?
at the bottom of the meniscus
What is the volume of liquid in a cylinder?
VariablesD = Cylinder diameter [L].Dbot = Cone bottom diameter [L].Dtop = Cone top diameter [L].h = Cone height [L].L = Cylinder length [L].T = Top width of liquid in cylinder [L].y = Liquid depth in sphere or cylinder [L].z = Horizontal to vertical side slope of cone. zDbot.Ø = Angle representing how full the cylinder is [radians or degrees]. An empty cylinder has Ø=0o, a cylinder with Ø=180o is half full, and a cylinder with Ø=360o is completely full.
What is the line on the graduated cylinder called?
meniscus
What is the curved line that forms when water is in a graduated cylinder?
This line is called the meniscus.
On a 95 F-150 Ford truck with a 4.9 6-cylinder is the top or the bottom line to the transmission from the radiator the return line?
The top line is always the return line, The cooler has to fill from the bottom or the fluid would get airated.
