For the correct reading, read off the base of the meniscus.
Surface tension between the liquid and the cylinder's inner circumference will raise the reading and give an erroneous reading.

You set the grad cylinder on a flat level surface, then you kneel or crowch down so that you are eye level with it. Then you look at the bottom of the curve in the liquid, known as the miniscus. The bottom of the miniscus is where you read the volume at. It is sometimes helpful to hold a dark piece of paper behind the cylinder, of you can color a black spot onto an index card of a folded piece of paper.

I used this method in my science lab class
1. Set the cylinder on a horizontal table
2. Read the level of meniscus, keepin your eyes directly ahead the meniscus, on the lowerpoint for a liquid like an aqueous solution, upper point for mercury
3. To get rid of parallax, tear a piece of paper and make a horizontal slit on it. Keep the paper on the cylinder and try to get the reading of liquid level through the slit.

Try to get eye level with the cylinder, and look at at the meniscus. Wherever the meniscus is at its lowest point, is the correct reading.

Dumb question. you go with the flattest factor of the liquid. In water (and maximum different beverages), it would be the backside. For mercury, it would be the best. have exciting troublesome your instructor in this one. Theoretically, there may be a miniscule distinction in case you skipped over the curvature, so that's recommended to degree the two "a" and "b". i don't understand every physique who desires this lots precision, nonetheless.

read from the bottom of the meniscus (that little curvy thing that comes from liquid adhering to the glass).

Setting the cylinder on a flat, level surface at eye level. (you may have to crouch down to get it at eye level.)

read the miniscus.. the bottom of the curve of the liquid
