What molecular attraction causes surface of the water to curve inside a glass?
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.
What should you look at to measure a volume of water in a graduated cylinder?
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.
If water splashes out of a graduated cylinder during a measurement of the volume of pennies Will it affect the results?
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.
What is the bottom of the curve of liquid in a graduated cylinder?
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)
How is the meniscus used in measuring the volume of liquids?
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.
Explain Why is the surface of water in a graduated cylinder curved?
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.
Which property of water causes a curved surface?
Adhesion is the property of water causes the curved surface
When using the measuring cylinder do you talk the measurement at the side of the cured surface or 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).
What is the curved surface of water in a burette called?
The curved surface of water in a burette is called the meniscus. It is caused by the surface tension of the water interacting with the walls of the burette.
Why was the surface of a Roman road curved?
The surface of a Roman road was curved to make water run off.
What is the meniscus rule used for?
The meniscus rule is used in chemistry to accurately measure the volume of a liquid in a graduated cylinder. It involves reading the bottom of the curved surface of the liquid level to get a more precise measurement.
Explain why the surface of water in a container is not flat but curved?
Surface tension.
When water is in a container the surface of water is curved. this curve is called?
convex
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.
When water is in a container and the water is curved What is the curve called?
This is called the meniscus. The meniscus is caused by the high surface tension of water.
How is Bernoulli's principle related to airplanes?
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.
When water is in a container the surface of the water is curved. this curve is called the?
The meniscus - the upward curve of a liquid in a narrow vessel.
