Assuming that the liquid in the beaker is water.... Due to the structure of water (two hydrogen, one oxygen), it has a slight negative charge near the oxygen atom an a slightly positive charge near the hydrogen atoms. These slight charges allow the edges of the water to cling to the sides of the beaker, thus creating a meniscus. Some liquids, like Mercury, actually would create a reversed meniscus (compare an alcohol thermometer with a mercury one).
The sides of the liquid in a beaker go up at the edges due to a phenomenon called surface tension. This occurs because the molecules at the surface of the liquid are attracted more strongly to each other than to the surrounding air. as a result, the liquid forms a meniscus shape.

Where do you read the meniscus?
The meniscus of a liquid is read at the bottom of the curve that forms at the liquid's surface in a graduated cylinder or a similar container. To determine the volume of the liquid accurately, it is important to read the measurement at the lowest point of the meniscus.
How do you read meniscus on a graduated cylinder?
All liquids have a surface tension. This tension creates a meniscus or curve on the surface, most noticeable in small diameter tubes or cylinders. The meniscus of water curves up the sides of the cylinder, while heavy liquids like mercury curves down the cylinder. You should always measure light liquids at the bottom of the meniscus and heavy liquids at the top of the meniscus.
Why does meniscus of water in glass curves upwards?
The meniscus of water in a glass curves upward due to surface tension. Water molecules are more attracted to the glass than to each other, causing them to climb up the sides of the glass. This creates a concave meniscus shape.
Why is it necessary to scratch the sides of the beaker for crystals to form?
Scratching the sides of the beaker provides a rough surface for crystal molecules to attach to, promoting nucleation and crystal growth. The scratches create sites for the crystals to start forming, which helps to speed up the crystallization process and yields larger crystals.
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 a meniscus used for?
the meniscus is not actually used for any thing water has certain properties that cause it to kind of climb up the sides of things it is inside of the meniscus is what this small amount of water is called
Why does water form a meniscus when it is put into a glass beaker?
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.
What liquid's meniscus curve up?
Water's meniscus curves up. Mercury's meniscus curves down.
Where do you read the meniscus?
The meniscus of a liquid is read at the bottom of the curve that forms at the liquid's surface in a graduated cylinder or a similar container. To determine the volume of the liquid accurately, it is important to read the measurement at the lowest point of the meniscus.
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)

The meniscus of water curves up the sides of the cylinder, while heavy liquids like mercury curves down the cylinder. You should always measure light liquids at the bottom of the meniscus and heavy liquids at the top of the meniscus.
What is the curve of the top surface of water in a graduated a graduated cylinder called?
Adhesion is responsible for the surface of the water in a graduated cylinder that is slightly curved at the sides.
What is a substance whose meniscus would curve downward?
Mercury's meniscus curves down. Water's meniscus curves up.
Does Liam go out with Tracy beaker?
No, Liam does not end up in a romantic relationship with Tracy Beaker in the "Tracy Beaker" series. Their relationship is mainly portrayed as a close friendship and mutual support for each other.

WherE is the stink bomb in big nate island poptrapica?
Well, actually, you have to make the stink bomb. You go to the science lab and to the beaker with the test tubes nest to it. You click on the beaker and it will show up with three colors of liquid. you but the boiler that is underneath the beaker to 4, and add the colored liquids to the beaker. What you want to do is create a grayish green color with all of the colors mixed. Fill up the beaker with the colors, though, otherwise it won't work. So, you fill up the beaker with the colors until it is full and it has a grayish green color to it.
How do win on the Tracy beaker party game?
you go on the cbbc web and in the search bow you type tracy beaker returns and then it should come up then you need to get all the upgrades to do it
