A single coin will not change the water level in the graduated cylinder enough to give a precise measurement of its volume. why was it possible to modify the experiment to use several coins?

Because when you put dozen of coins water level will change enough to mesaure it, then volume you got by such mesauring should be divided by number of coins. that way you will get volume of single coin.

What is a sample space for an experiment?
It is the set of all possible outcomes of the experiment.
What do you call all possible outcomes of an experiment?
All possible outcomes of an experiment is known as a sample space. This will include an exhaustive list of all the possible results to be achieved.
How many variables there be in an experiment?
As few as possible.
A precise measurement is one that?
Is as exact as possible
What is a possible outcome of an experiment rolling an eight or picking 3dice from a jar?
Both rolling and eight or picking three dice from a jar could be possible outcomes of an experiment.
If a graduated cylinder was not correctly calibrated how would it affect the results of a measurement?
This is one of those oddly obvious questions. If a graduated cylinder was not correctly calibrated, then it would yield an incorrect meaurement when you use it. Withouth calibration, you wouldn't know if it was reading high or low. It might be possible to make precise measurements, but precision is a different quality from accuracy. Being able to measure to a tenth or hundredth of a mililiter doesn't mean much is your measurement is off by half a mililiter.
Which graduated cylinder is more precise a 25 mL or 100 mL?
As far as sig figs are concerned, the graduated cylinder will yield a measurement that is both more precise and accurate than is possible using an Erlenmeyer (precision and accuracy mean different things in science talk). Erlenmeyer flasks aren't really intended to be used for measurement of volume, as the width of the flask at the point of the markings introduces lots of error as you try and eyeball the level of fluid within it. The narrow column of a graduated cylinder will allow you to judge volume far more accurately since a difference in the height of fluid in one of these will result in a lower overall difference in volume when compared to the Erlenmeyer.Keep in mind though, that just because a graduated cylinder contains a certain volume doesn't mean that it will deliver that entire volume to another container, since some of the liquid inevitably clings to the sides. This isn't a problem is you are simply trying to measure volume, but if you are trying to pour an exact volume into another container you need to use another method to do so. In this case your best bet is to pipette.
Total possible outcomes?
Is the number of all possible outcomes of an experiment. The number depends on the experiment.
What are the possible jobs for graduated in Manchester?
Some possible jobs for graduates from Manchester University depend on their degrees and work experience and what degree classification they graduated with.
What are the errors in filtration experiment?
Possible errors in filtration experiment
What is a sample space for an experiment?
It is the set of all possible outcomes of the experiment.
What is the volume of a cylinder in cu ft?
If you have the radius and the height in feet, you can calculate the volume as:V = pi x radius squared x height (If you have the diameter of the cylinder, the radius is one-half the diameter.)
What is a possible result of an experiment?
Outcome
When a controlled experiment is not possible why do scientists try to identify as many relevants as possible?
to gather data from data to create an controlled experiment
What do you call all possible outcomes of an experiment?
All possible outcomes of an experiment is known as a sample space. This will include an exhaustive list of all the possible results to be achieved.
Is measurement without mathematics possible?
Measurement is not possible without numbers and:A number is a mathematical object used in counting and measuring.
Is a controlled experiment always going to be possible?
No it will not be all ways possible.
