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).

Where do you read the meniscus?
Take the measurement at the bottom of the meniscus, not where it arches up against the sides.
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.
Is the curve at a liquids surface by which you measure the volume of a liquid?
The meniscus is the curve at a liquid's surface by which one measures the volume of the liquid. A meniscus can be concave or convex depending on whether it is attracted to itself or 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!
Where should a beaker be placed with respect to the flame for the most efficient heating on Bunsen burner?
The most efficient, and safe, place for a beaker to be heated is above the flame. Have the beaker held up by the proper metal stand and have it held so that the flame is grazing the bottom of the beaker. Be careful though, the flame should only graze the bottom of the beaker so that the chemical doesn't heat up too quickly.

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
What liquid's meniscus curve up?
Water's meniscus curves up. Mercury's meniscus curves down.
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)

What happens when you put a beaker over a candle and why?
Burning is a process that uses up oxygen. When all the oxygen in the beaker is used up, the candle will go out.
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.
Why does water form a meniscus when it is put into a glass beaker?
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.
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
How do you get 9 liters from a 10 and 7 liter beaker?
Fill the 7 beaker and pore contents into 10 beaker. Mark where the contents come up to on the 10 beaker. Fill the 10 beaker up and pour off the top of it into the 7 beaker until you are down to the mark. You will now have 3 litres in the 7 beaker. Mark where it comes up to. Empty the 10 beaker. Pour the 3 litres in the 7 litre beaker into the 10 litre beaker. Fill the 7 litre beaker up to the 3 litre mark and pore it into the 10 twice more. You now have 3*3=9 litres in the 10 litre beaker. QED.
