The meniscus is the name for the way that water forms a concave curve at it's surface. This is because of the cohesive and capillary properties of water.
The force of adhesion between water and glass molecules is greater than the force of cohesion between two water molecules.This causes the surface of the water to be curved. This curved surface is called a meniscus.
Place the cylinder on a flat surface. Read the volume contained in a graduated cylinder or volumetric flask, by comparing the bottom of the meniscus (the curved surface of the liquid),at eye level, to the nearest graduation or ring.
Measuring the volume of pennies by their displacement requires that only water actually displaced by the pennies is measured. Unless the water was at the very top of the cylinder both before and after the pennies are added, splashed water will make the measurement invalid.Because surface tension forms a curved surface at the top of the water, it is advisable to have the cylinder only partly filled, and measure the level at the same part of the curved water surface both before and after the pennies are added. This will improve the accuracy of measurement.
Since the surface of water rises up to the sides of the cylinder, the low point is in the center of the surface. (Volume is assumed unless boiling or melting points are stated)
AnswerA meniscus is when the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. This causes the liquid to "stick" to the side of the container, creating a curve. The volume must be read at the bottom of the meniscus.
it is probably called figure it out, it is curved because glass is sticky. When you measure the volume from a graduated cylinder, measure at the bottom of it. It is called the meniscus.
Adhesion is the property of water causes the curved surface
I think you are talking about a graduated cylinder. When measuring liquids in a grad. cylinder you should read at the bottom of the miniscus ( the curved surface of the water or other liquid).
The surface of a Roman road was curved to make water run off.
Surface tension.

This is called the meniscus. The meniscus is caused by the high surface tension of water.
Bernoulli showed (using water models) how flow over an airfoil (the top surface curved more than the bottom = shape of aircraft wing) lowered the pressure on the top surface, thus producing lift.
The meniscus - the upward curve of a liquid in a narrow vessel.
