What is the scientific name for the curved water surface above the rim of a glass?

The curve you see on top of a liquid in a cylinder is called the meniscus and is due to the difference between the attractive force between the liquid molecules themselves and between the liquid molecules and the wall of the cylinder, as well as capillary action. When the molecules of the liquid have a greater attraction to the cylinder wall than to themselves, the meniscus is concave and the surface of the liquid curved downwards. Water drawn up a narrow glass cylinder has a concave meniscus. When the molecules of the liquid have a greater attraction to themselves than to the cylinder wall, the meniscus is convex and curves upwards. Mercury in a glass thermometer or barometer has a convex meniscus.

water has a tendency to "cling" to the side of the graduated cylinder, or whatever measuring device you use. when reading the value, you must look across and take your reading at the bottom of the meniscus
|-__-| outside vertical lines are the measuring device. dashes is the water clinging to the walls. and the underscore is the bottom of the meniscus and where you would read the value.

What is a curved glass that makes things look closer than they really are?
Curved glass that makes things look larger or closer is a magnifying glass.
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.
Curved glass that bends light rays?
A lens is a curved glass that refracts or bends light rays. The two principal types of lenses are convex and concave.
A curved piece of glass is called a?
a shard
What is a curved surface on a liquid called?
A meniscus, but whether it has a positive curve or a negative one depends on whether it wets the glass.
When was The Curved Glass created?
The Curved Glass was created in 2001.
Why does a glass bottle magnify words?
Because the surface of the bottle is curved - which bends the light passing through it - just like a magnifying glass does.
What is curved glass called?
It's just called curved glass.
Why is there a curved surface a the top of a water glass instead of straight across?
The phenomenon of the curved water is due to "inter-molecular forces". That is, water is attracted to itself by virtue of the charge difference across the water molecule, much like a little magnet. So as you (slowly) add water to a full glass, rather than sliding off and out of the glass, the new molecules are attracted to the molecules already present in the glass and will build up into a curved surface. The reason the surface is curved rather than, say, cylindrical, is due to gravity. The center of the glass can hold the most water weight, with a gradually decreasing weight capacity as you move toward the edges.
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.
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.
What is a curved glass that makes things look closer than they really are?
Curved glass that makes things look larger or closer is a magnifying glass.
How is a magnifying mirror made?
A round piece of plate glass is heated and slumped over a curved steel form then silvered on the convex side. Better ones were made by grinding and polishing a convex surface to one side of flat window glass then silvered on the curved side.
Can you give me an example of how light refacts?
Light refracts when the light photons changes medium, such as from air into glass. A curved glass surface will result in different levels of refractions and hence the different colors.
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 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.
How can one break a glass bottle?
You can break a glass bottle by dropping it onto a hard surface. It is especially easy if you are holding it high above the surface. You can also break a glass bottle by throwing it, stomping on it, or running it over with a car.
