Question

Which instrument is used to measure the specific volume of liquid?
A. Pipette
B. Manometer
C. Balance
D. Calorimeter

Answer 1

Hint: 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 first understand the structures and functions of all the instruments mentioned in the options:
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.
Manometer: manometer is an instrument that is used for measuring pressure. it comes in a variety of configurations in order to satisfy the level of sensitivity of scale required.
Balance: a balance is a measuring device that can be used to measure the weight of a given object. Similar to manometers, it is available in a number of configurations to satisfy the different sensitivities required.
Calorimeter: Calorimeter is an instrument that is used to measure the heat of chemical reactions, heat capacities of substances as well as physical changes of objects. It is highly useful in the fields pertaining to thermodynamics.
After understanding the form and function of the different instruments mentioned in the options, we can conclude that the instrument is used to measure the specific volume of liquid is a pipette

Hence, Option A is the correct option.

Note: 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.
