When a liquid is held in a vessel, the water adheres to the side of the vessel. So when the amount of liquid held by the vessel is less than the full amount the vessel will hold, the liquid level rises where it touches the vessel. It "sticks" to the side of the vessel hard enough to be above the top of the liquid. This is called a negative meniscus. When the level of the liquid is higher than the top of the vessel (but doesn't overflow the top due to the surface tension of the liquid), then there is a positive meniscus.
What else can I help you with?
When measuring you do the measurement from the bottom of the meniscus?
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.
What property of water causes the hydrometer to be read at the level of the meniscus?
The property of water that causes the hydrometer to be read at the level of the meniscus is surface tension. The meniscus is the curved surface of the water in the hydrometer caused by the attraction between water molecules and the walls of the hydrometer. Reading at the bottom of the meniscus helps to ensure an accurate measurement.
How is a meniscus used in measuring?
As the diameter of the container decreases, the meniscus becomes more pronounced. The meniscus may be convex (curving upward) or concave (curving downward). Most of the time you will find that the meniscus is concave. The most notable exception is the meniscus that forms from mercury. When taking measurement readings it is important that the reading is done properly. The following rules must be adhered to: I. Read the meniscus at eye level. Do not read the meniscus from above or below eye level. Significant measurement errors may occur II. Read the bottom of a concave meniscus and the top of a convex meniscus.
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
Why should liquid volumes be read at eye level?
Liquid volume readings should be at the bottom of the menicus or at the level of the liquid in the middle of the container. The accuracy of the reading may vary slightly with the viscosity of the liquid and the diameter of the container.
What part of the meniscus do you measure from?
You measure from the bottom curve of the meniscus.
What is the lowest point of the water level in a graduated cylinder called?
It's called Ya Mum's Panis
In which diagram do you not see a meniscus?
You do not see a meniscus in Diagram C, as the liquid surface is flat and level with no curvature at the edges.
How do you use volume and meniscus in a sentence?
To measure the volume of a liquid accurately, it is important to read the meniscus at eye level.
When measuring you do the measurement from the bottom of the meniscus?
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.

What does meniscus mean in science?
meniscus is when you fill the beaker upwith liquid. when yo go down to look at the beaker with eye level, you see a dip. that's the meniscus. -used in science

Liquid volume readings should be at the bottom of the menicus or at the level of the liquid in the middle of the container. The accuracy of the reading may vary slightly with the viscosity of the liquid and the diameter of the container.
What is the zero correction and meniscus correction in hydrometer analysis?
· Zero Correction (Fz): If the zero reading in the hydrometer (in the control cylinder) is below the water meniscus, it is (+), if above it is (-), if at the meniscus it is zero.· Meniscus Correction (Fm): Difference between upper level of meniscus and water level of control cylinder.
What is the meniscus of a thermometer?
The meniscus of a thermometer is the curve seen at the surface of a liquid in the thermometer tube. It is caused by surface tension and capillary action, and the measurement of temperature is taken at the lowest point of the meniscus. Reading the temperature correctly involves ensuring that the eye is at the same level as the meniscus.
