Meniscus is the curved surface of a liquid in a container; to measure correctly the volume in a graduated cylinder it is necessary to take into account the meniscus type, convex or concave.
What else can I help you with?
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.
How do you read meniscus on a graduated cylinder?
All liquids have a surface tension. This tension creates a meniscus or curve on the surface, most noticeable in small diameter tubes or cylinders. The meniscus of water curves up the sides of the cylinder, while heavy liquids like mercury curves down the cylinder. You should always measure light liquids at the bottom of the meniscus and heavy liquids at the top of the meniscus.
Is the curve at a liquids surface by which you measure the volume of a liquid?
The meniscus is the curve at a liquid's surface by which one measures the volume of the liquid. A meniscus can be concave or convex depending on whether it is attracted to itself or the glass.
What meniscus is being read if you measuring the volume of dark colored liquids?
1.read the bottom of the curve 2. you must read the meniscus at eye level
What are the two liquids that show upper meniscus?
Mercury and water are two liquids that show an upper meniscus when measured in a graduated cylinder or other narrow container. This means that the liquid forms a concave shape at the surface where it meets the container's walls.

What laboratory apparatus does not have a meniscus?
A meniscus it the curve of a liquid when it adheres to the side of its container. Only glassware used for measuring volumes of liquids have a meniscus. The scale.
Is the meniscus the same height for every liquid?
No, the meniscus is not the same height for every liquid. The curvature of the meniscus depends on the cohesive and adhesive forces between the liquid molecules and the container surface. Different liquids will have different interactions with the container, leading to varying meniscus heights.

1.read the bottom of the curve 2. you must read the meniscus at eye level
How do you measure the volume of liqiud?
When a liquid is filled in a cylinder, the liquids usually form a bubble called meniscus. Then you measure the lowest point of the meniscus and record the measurement.
U shape cause at top of beaker when measuring volume of liquids?
meniscus (spelling)
What are the two liquids that show upper meniscus?
Mercury and water are two liquids that show an upper meniscus when measured in a graduated cylinder or other narrow container. This means that the liquid forms a concave shape at the surface where it meets the container's walls.
What is the curve along the top of a liquids surface?
Meniscus.
Would a graduated cylinder be read at the middle of a meniscus?
The answer depends on the liquid, or more specifically, how the surface tension in the liquid affects the meniscus. It should be the top of the meniscus for liquids such as mercury but the bottom for liquids such as water or alcohol.
