How is it possible to get three precise but inaccurate measurement of the same volume of water?

Definition of Precision: Referring to how close a group of measurements are to each other.
Accuracy: Refers to how close the measurement is to the true or accepted value.
If the volume of the water was 20 L and I measured it wrong one and got 19, measured it again and got 19, and then measured it a third time and got 19, that would be a PRECISE measurement, since you got the same result three times in a row. It's INACCURATE because it isn't the CORRECT measurement.
Hope that helped!

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 the volume of a cube that has a measurement of 3.5 on each edge?
The volume of a cube with a measurement of 3.5 on a side is 42.875.
How do you convert length to volume?
Length and volume are not equivalent measurements. Length is a two dimensional measurement while volume is a three dimensional measurement.
What would be the units of measurement for volume and mass?
In the metric system, the units of measurement of Volume is the Liter (sometimes spelled Litre) and the measurement for mass would be the gram. In the American system, the units of measurement for Volume is the ounce, and for mass would be the pound.
What is a measurement expressed in m3?
Volume
Should be used to make a precise measurement of liquid volume?
gradulated cylinder
What h of the following should be used to make a precise measurement of liquid volume?
Graduated cylinder
What possible sources of error for the barfoed's test?
Possible sources of error for the Barfoed's test include inadequate mixing of the reagents, inaccurate measurement of the sample volume or reagent volume, contamination of reagents or equipment, incomplete boiling or heating of the test tubes, and improper timing of the reaction.
What tool used for measuring precise volumes of liquids?
A graduated cylinder is a common tool used for measuring precise volumes of liquids in a laboratory setting. It has markings along its length that allow for accurate measurement of the liquid volume.
How many liter in kilo gram?
Not possible to answer - a litre is a measurement of volume, while a kilogram is a measurement of weight!
What instrument which would be more accurate for measuring the volume of a liquid?
A graduated cylinder would be more accurate for measuring the volume of a liquid compared to a beaker. This is because graduated cylinders have more precise volume markings and allow for more accurate readings due to their narrow and uniform shape.
What is the error can be formed using beaker?
An error that can be formed when using a beaker is inaccurate volume measurements, as the markings on the beaker may not be precise. It is important to use a graduated cylinder for more accurate volume measurements. Additionally, using a beaker for precise measurements of small volumes can also lead to errors.
Which is more precise a graduated cylinder or a breaker?
A graduated cylinder is typically more precise than a beaker because it has measurement markings with smaller increments, allowing for more accurate volume readings. Beakers are generally used more for approximate measurements and mixing rather than precise volume measurements.
How does the use of a burette make a titration precise?
A burette allows for precise and accurate measurement of the volume of titrant added during a titration. The graduations on the burette permit the volume to be read to high precision, enabling accurate determination of the endpoint of the titration. This facilitates precise calculation of the concentration of the analyte in the solution being titrated.
How many cubic foot in one square mile?
Not possible to answer - a cubic foot is a measurement of volume, a square mile is a measurement of area!
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 6000 cubic feet is what in feet?
It is not possible to equate feet (a measurement of length) with cubic feet (a measurement of volume).
