Accuracy is a comparison of a measured value to the accepted, or true, value. Suppose the volume of the liquid had actually been 5.44 mL.

In which of the following examples would the precision of a thermometer be more important than its accuracy? a) Determining, the identity of an unknown compound by comparison of its measured melting point to a reference table
Accuracy is a measure of how close your measured value is to the true value or other standard. Although sometimes we use qualitative (verbal) words to describe the accuracy (such as good accuracy and bad accuracy), a quantitative (numerical) measure is more useful when comparing measuring devices based on laboratory data.

For instance, a 250 mL beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 mL of volume. These marks are not intended for obtaining a precise measurement of volume (a graduated cylinder or a volumetric flask would be a more appropriate instrument for such a task), but rather an estimation. Most beakers are accurate to within ~10%.

(The accuracy of the graduated cylinder is further hampered by the fact that the other techniques deliver the specified volume, whereas the graduated cylinder contains the specified volume, and a small amount of Coke or Diet Coke is left behind in the graduated cylinder when the liquid is poured into the beaker for weighing.Aug 29, 2020 · Beaker B has a height that is twice the diameter. Moreover, beaker C has comparatively a small height, and it is named as a crystallizer. Due to the presence of a spout, a beaker cannot have a lid. But in general use, we can cover the beaker with a watch glass. That is to prevent contaminations and to avoid the loss of components inside.
