∙ 13y agoFor a fluid that curves down like water you read from the bottom of the meniscus. If the fluid curves up like mercury you read from the top of the meniscus

∙ 6y agoFor a concave memiscus the measurement is under the meniscus.
For a convex memiscus the measurement is over the meniscus.

Why are there lines on a graduated cylinder?
calibration mark
Would you use a beaker or a graduated cylinder to measure isopropyl alcohol?
Graduated Cylinder.
How do you read a graduated cylinder while using the meniscus?
The most accurate way to read a graduated cylinder is to place it on a flat surface. Bend down so you are eye level with the Meniscus Line, the line that is formed by the border between the unfilled portion of the cylinder and the top of the liquid. The very lowest part of this line is where you read the measurement. The markings are in whole numbers, 1, 2, 3, etc., with 10 lines between each number.
Which property of water causes water to curve in a graduated cylinder?
With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. So the liquid "sticks" to the side of the container. A few liquids have a "backwards" meniscus. An example is mercury. If you put mercury in a test tube, it would be higher in the middle than at the edges.
What graduate cylinder would be most accurate for measuring the water?
This is called a meniscus, from the greek work for 'crescent'. You should meaure from the bottom of it when it is concave (like a smile) or the top when it is convex (like a frown).
If you place water in a plastic graduated cylinder would it have a meniscus?
Formation of meniscus is a general phenomenon.

What is the curve of the top surface where the water is in a graduated cylinder called?
that would be the meniscus
How would you find the volume of a glass of water?
you carefully poor the water into a graduated cylinder and meassure at the lowest point of the meniscus.
Which graduated cylinder would be the best one to use to measure exactly 15ml of water Why?
Either a 100 mL or a 50 mL The 50 mL is better because you can see the meniscus against the graduated lines of the cylinder better.
What would you use to measure using a graduated cylinder?

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 scientific name for the curved water surface above the rim of a glass?
The curve you see on top of a liquid in a cylinder is called the meniscus and is due to the difference between the attractive force between the liquid molecules themselves and between the liquid molecules and the wall of the cylinder, as well as capillary action. When the molecules of the liquid have a greater attraction to the cylinder wall than to themselves, the meniscus is concave and the surface of the liquid curved downwards. Water drawn up a narrow glass cylinder has a concave meniscus. When the molecules of the liquid have a greater attraction to themselves than to the cylinder wall, the meniscus is convex and curves upwards. Mercury in a glass thermometer or barometer has a convex meniscus.
What scientific tool do scientist use to measure volume?
You would use a graduated cylinder
