Question

What is the tool that scientists commonly used to measure liquid volume?

Answer 1

Hint :We know that the volume is a three dimensional quantity whose measurement needs some more accurate devices. The amount of space taken up by a body is called its volume. It is measured in cubic units. Specific volume of a liquid is the physical property which can be understood as the ratio of the volume of the liquid to the total mass of the liquid. To put it in simpler terms, it is basically the reciprocal of density of the substance.

Complete Step By Step Answer:
Before we delve into this question, let us firstly understand the structures and functions of all the instruments mentioned; we should be aware of the difference between volume and capacity. They are differing terms. Volume is the amount of space occupied by an object while capacity is the ability of an object to hold a substance. To answer these types of questions, we must know the basics of measuring devices
Pipette: Pipette can be explained as a media dispensing device that is effective in keeping track of volumetric transfer of material while in operation. It is usually a glass based tube like structure. Pipettes exist in various configurations which vary in the levels of precision and accuracy required.
Graduated Cylinders: Generally uncertainties are in the tenths place, since the index markings are at each integer.
Erlenmeyer Flasks: Generally uncertainties are fairly high depending on the flask volume, so this is mainly a reaction vessel but can be used to approximate volume.
Volumetric Flasks: Often calibrated for containing or delivering a specific volume, great for measuring exact volumes. These often have uncertainties in the hundredths place, such as $ 100.00\pm 0.02\text{ }mL $ when you properly measure to the index mark.
Burettes: Fairly common; used in titrations fairly often, with an uncertainty usually in the hundredths place. For example, $ 100.00\pm 0.10\text{ }mL~ $ for a to-deliver burette.

Note :
Remember that to be more specific to the type of pipette to be used; we can say that ‘volumetric pipette’ can be used for measuring the specific volume of a liquid. This is because volumetric pipettes have long necks which decrease the errors in measurement. Don’t make solutions too lengthy by adding unnecessary information. We should only analyse the functions of the measuring devices.
