Why does water form a meniscus when it is put into a glass beaker?

∙ 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.

Water forms a meniscus in a glass beaker due to surface tension, adhesion, and cohesion. The water molecules are attracted to the glass molecules (adhesion), causing them to climb up the sides of the beaker. Additionally, water molecules are attracted to each other (cohesion), causing the surface of the water to be slightly curved.

∙ 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 water form a convex surface if you slightly over fill the glass?
Water forms a convex surface when overfilled in a glass due to surface tension, caused by the cohesive forces between water molecules. This makes the water "climb" the edges of the glass, creating a convex meniscus.
Why does a concave meniscus form when water is in a graduated cylinder?
A concave meniscus forms in a graduated cylinder with water due to adhesive forces between the water molecules and the walls of the cylinder. This causes the water to cling to the walls, resulting in a concave shape.
How is water droplets formed in the inner most surface of the beaker?
Water droplets form on the inner surface of a beaker when the water vapor in the air comes into contact with a cold surface, causing it to condense into liquid water. This occurs due to the temperature difference between the cold surface of the beaker and the surrounding air.
Is oil and water in a beaker classified as a solution?
No, oil and water in a beaker would not be classified as a solution. Oil and water are immiscible, meaning they do not mix together to form a homogeneous solution. Instead, they separate into distinct layers due to differences in polarity.
When you boil a beaker of water over a Bunsen burner will it become a gas?
No, when you boil a beaker of water over a Bunsen burner, the water will not turn into a gas. It will reach its boiling point (100°C at sea level) and turn into steam, which is the gaseous form of water.
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?
A concave meniscus forms in a graduated cylinder with water due to adhesive forces between the water molecules and the walls of the cylinder. This causes the water to cling to the walls, resulting in a concave shape.
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 commonly used in laboratories to hold, mix, or heat liquids. They are transparent, allowing for easy observation and measurement of liquid volume. Beakers also have a spout for easy pouring and a flat bottom for stability.
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, 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.
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.
