Why are there lines on a graduated cylinder?
calibration mark
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 is the most accurate way to read graduated cylinder?
at the bottom of the meniscus
Up to what significant figures can you measure the vo lume of the liquid with your graduated cylinder?
it depends on how much each gradient on the cylinder is worth. if it was 1ml per line then you would round to nearest mL
What is used for graduated cylinder?
A graduated cylinder is a piece of laboratory glassware used to accurately measure out volumes of chemicals for use in reactions. They are generally more accurate and precise for this purpose than beakers or erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipet. They come in a variety of sizes for different volumes, typically 10 ml, 25 ml, 50 ml, or 100 ml and up to as large as 1 or 2 liters. Determine the volume contained in a graduated cylinder by reading the bottom of the meniscus at eye level.
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.
What is beaker that measures volume?
I've used a lot of beakers, and they're marked on the side. You just fill it to the line you want to use.

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."
On a hot day a student observes water drops on the outside of a bottle of cold water. Explain this observation in terms of the concept of thermal energy.?
Use the water displacement method. You need a graduated cylinder and some water. Fill the graduated cylinder with enough water so that when you place the rock in the graduated cylinder it will cover the rock. Read the meniscus (the slightly curved line of the water) at eye level. Record your measurement of the water in the graduated cylinder (in mL). Place the rock in the graduated cylinder and record your new measurement of the water line, again at eye level. Subtract the original measurement from the new one to get the volume of the rock.
On a graduated cylinder what does each line represent?

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.

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 bottom of the liquid line in a cylinder is called?
