Why does water form a meniscus when it is put into a glass beaker?
Wiki User
∙ 14y ago
Water in a graduated cylinder form a meniscus due to attraction between the water molecules and the glass and the water being repelled by the container. If it is repelled a convex meniscus will be formed and if attracted it will result of a concave meniscus.

∙ 14y agoThis happens because water "wets" glass. That is, the adhesive force between water and glass is greater than the cohesive force that exists between two water molecules. This causes some water to climb up the glass surface.
The phenomenon is greatly exaggerated for tubes of very small diameter. This is called capillary action and you can read about it more on wikipedia.

∙ 14y agoThe water forms a meniscus because of the way the cylinder is formed. The circular pattern gives off a meniscus shape. I HATE SCIENCE QUESTIONS!

Why does a concave meniscus form when water is in a graduated cylinder?
The force between glass and water are stronger than between water molecules
What is the use of glass beaker?
Glass beakers are usually used to hold chemical solutions, or a form of liquid.
Is oil and water in a beaker classified as a solution?
No. Oil and water would form a heterogeneous mixture. A solution is a homogeneous mixture.
Why did copper in the solution plate the spoon and no the beaker?
The copper and the metal of the spoon have a chemical attraction to one another and form bonds. Glass is essentially inert, and does not form bonds with metals in solution.
Water is to glass as correspondence is to what?
Water is to glass as correspondence is to...mailbag or epistolary novel. Something without form is contained.
How can you relate volume to a meniscus?
When measuring the volume of a liquid in a graduated cylinder, you read it at eye-level and at the bottom of the curve of the meniscus. This is true for water and aqueous solutions. Some "non-water" liquids do not form a meniscus in a glass cylinder. Also, water does not form a meniscus in a plastic cylinder.
Why does meniscus of water in glass curves upwards?
Adhesion to the test tube or cohesion of the liquid molecules causes the meniscus to form.
Why does a concave meniscus form when water is in a graduated cylinder?
The force between glass and water are stronger than between water molecules
Would condensation form on the outside of a beaker full of hot water why or why not?
No. The glass of the beaker, since it is hot, not cold, would not cause the ambient moisture to coalesce on the glass
Why doesn't soapy water bulge from the sides of a glass?
Water, as other liquids, has "surface tension" which tries to pull the water into the smallest volume. When put into a glass the surface of the water behaves as if it has a skin. However, that part around the circumference of the glass where the water touches the glass tries to climb the glass, so creating a "meniscus". If you add soap to water its surface tension is greatly reduced so it is less able to form a curved upwards meniscus where it meets the glass.
What is a meniscus is and how it is used to measure liquids?
A meniscus is the curve of a liquid. Like when you are filling a glass of water, if you continue to put water in the glass after it has reached the top, then the extra water will go above the glass in a curved shape. When you are measuring liquids in for example a graduated cylinder, you would take the measurement from the bottom of the meniscus. I hope this helps!
What is the use of glass beaker?
Glass beakers are usually used to hold chemical solutions, or a form of liquid.
Which property of water results in a meniscus?
Adhesion due to the polarity of the water molecule.
Is the meniscus the same height for every liquid?
No. Water is one of the few liquids that have enough surface tension to form a meniscus
Why does the the meniscus in a graduated cylinder filled with water curve downward?
The water is slightly attracted to the glass walls of the cylinder and is to some slight degree climbing up the walls in a form of capillary action (the tube itself can be regarded as a large capillary).
What is the singular form of meniscus?
The word meniscus is the singular form; the plural form is menisci.
Why does ice often form on he outside of a glass beaker containing dry ice?
A beaker of Dry Ice will have VERY cold, glass walls. The moisture in the surrounding air comes into contact with the cold surfaces, condenses and freezes on them. Thus, your ice formation on the beaker.
