What is the little dip in the liquid in a graduated cylinder called?
The Meniscus When observing a volume of a liquid in a graduated cylinder, graduated pipette, or buret, read the point on the graduated scale that coincides with the bottom of the curved surface of the liquid. The curved surface of the liquid is called the meniscus.
How do you read a meniscus in a graduated cylinder?
Follow the lowest point at the surface of the water to the wall of the graduated cylinder. Read the volumetric scale at this point. If you have trouble seeing the meniscus, try holding a black card against the opposite side of the graduated cylinder at the same height as the water.
When you read the volume of a liquid in a graduated cylinder above the eye level will you get a lower or higher reading?
Keep in mind that when reading the measurement, you need to keep the graduated cylinder on a level desk, lower your eyes to the level of the meniscus, and you read the volume accordingly. Be sure to include one point of estimation in your reading (see sample reading shown on the left).

What is the curve of water in a graduated cylinder called?
A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.
Why is the surface of water in a graduated cylinder curved?
Again, since polar molecules like to stick together, the water in a glass tube will actually tend to stick to the sides of the tube! You can see this at the top of the graduated cylinder, where the water will slightly creep up the sides and form a curve, which is the meniscus.
What do the lines on a graduated cylinder indicate?
A graduated cylinder, also known as a measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured.
What is the meniscus of water?
What is a meniscus? A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.
What are the lines on a graduated cylinder called?
The graduated cylinder will usually have heavy markings at 10, 20, 30, etc. milliliters. There are smaller markings in between the larger units called graduations.
When measuring the volume of a liquid in a graduated cylinder look at the?
When a liquid is placed into a graduated cylinder, the surface takes on a curved shape. This curve is known as a meniscus. The graduated cylinder is calibrated so that reading the bottom of the meniscus, when viewed at eye level, will give accurate results.
How do you measure liquids in a graduated cylinder?
Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.
What is the curved surface of a liquid in a container called?
The meniscus (plural: menisci, from the Greek for "crescent") is the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension.
What shape is the surface of water?
Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer.
What is the curved surface of water called?
A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.
What are the lines called on a graduated cylinder?
The graduated cylinder will usually have heavy markings at 10, 20, 30, etc. milliliters. There are smaller markings in between the larger units called graduations.
What is the line on a beaker called?
This curve is known as a meniscus.
What is meniscus in water?
What is a meniscus? A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.
Why does a meniscus form in a graduated cylinder?
Again, since polar molecules like to stick together, the water in a glass tube will actually tend to stick to the sides of the tube! You can see this at the top of the graduated cylinder, where the water will slightly creep up the sides and form a curve, which is the meniscus.
When using a graduated cylinder The liquid often forms a curve at the surface where along the curve should you measure the volume?
This curved surfaces is called the meniscus. A meniscus forms because the liquid molecules are more strongly attracted to the container than to each other. To properly measure the volume of a liquid in a graduated cylinder you must be at eye-level and read the bottom point of the meniscus.
When using a graduated cylinder for measuring a liquid What is the proper method quizlet?
How you should properly read a graduated cylinder? Place the container onto a flat surface, pour in the liquid, and read bottom of meniscus.
What does a graduated cylinder measure in?
milliliters A graduated cylinder measures in milliliters, which is a measure of volume. The English system equivalent is pints, quarts, and gallons.
What is a curved surface?
The curved surface is a rounded surface that is not flat. Curved Surface. Flat Surface. An object can have a curved surface all around it. Such objects have only one surface throughout.
Why is water curved in a graduated cylinder?
Glass molecules also happen to be polar. Again, since polar molecules like to stick together, the water in a glass tube will actually tend to stick to the sides of the tube! You can see this at the top of the graduated cylinder, where the water will slightly creep up the sides and form a curve, which is the meniscus.
Why does a meniscus form?
Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus.
Why graduated cylinder shaped that way?
The standard graduated cylinder has a narrow cylindrical shape, with each marked line showing your volume of liquid being measured. While they're generally more accurate and precise than laboratory beakers and flasks, they shouldn't be used to perform volumetric analysis.
What is a meniscus in water?
What is a meniscus? A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.
Why the liquid surface is curved?
Again, since polar molecules like to stick together, the water in a glass tube will actually tend to stick to the sides of the tube! You can see this at the top of the graduated cylinder, where the water will slightly creep up the sides and form a curve, which is the meniscus.
When using a graduated cylinder The liquid often curves up along the sides of the container?
This curved surfaces is called the meniscus. A meniscus forms because the liquid molecules are more strongly attracted to the container than to each other. To properly measure the volume of a liquid in a graduated cylinder you must be at eye-level and read the bottom point of the meniscus. 1.
