Question

Why is the meniscus level important for accurate readings of graduated cylenders?

oh yeah! , Also why must you re-zero a balance between each weighing of an objec? is it that important ........

oh thanks my teacher keeps telling me to re-zero everytime we did a lab with the balance. i was just asking myself that ...thanks

Answer 1

meniscus is basicly a curve of the water when you are trying ot measure something in like a beaker.... it can result in an inncacurate measurement if you do not take it in to account because if you are looking at a cylinder and the miniscus is curving upward you will measure to little amount of substance and if it is curving downward you will measure to much. You need to re zero a balance every time (or tare) because you have to make sure that your next measurement is just as accurate as the one before

Answer 2

when reading the liquid level in a graduated cylinder always read to the bottom of the meniscus. The cylinder must be kept vertical so that the meniscus is level, this will give the most accurate reading of the scale. a balance must be zeroed between uses because the balance may have been moved slightly which will affect its zero point.

Answer 3

if you don't read it at the meniscus then the measurement will not be correct and if you don't zero the scale then the scale might read .1 or some thing and this would screw up the whole experiment. Same with the meniscus, if your'e a little off the goes the whole experiment

Answer 4

Well, if you don't re-zero, your calculations are going to be off a little. Or hadn't you thought about that?

Answer 5

so you won't get a wrong reading?
