METHOD: LIQUID VOLUME MEASURING DEVICES.

Measuring the volume of a liquid is relatively straight forward. Since liquids take the shape of the container in which they are placed, a liquid whose volume is to be found can simply be poured into a graduated container such as graduated cylinder (Figure 3), that is, a container on which some scale has been etched. Graduated cylinders of various sizes, ranging from 10 ml to 1 L are commonly available in science laboratories for measuring the volumes of liquids.

Other devices, such as pipettes and burettes (Figure 4), are available for measuring exact volumes, especially small volumes. This is imperative, so students do not carry these misconceptions any further and develop a better understanding of mathematics.
