The plastic flask is needed for trace analysis on analytes at ppb levels that might be lost by adsorption on the glass surface.
A volumetric flask is used for measuring precise volumes of liquids because it has a narrow neck and a specific volume marking, allowing for accurate and consistent measurements.
A volumetric flask is a piece of laboratory glassware used in analytical chemistry for the preparation of solutions. It is made of glass or plastic and consists of a flat bottomed bulb with a long neck, usually fitted with a stopper. The stopper is normally made in a chemically resistant plastic such as polypropylene rather than glass. The neck has a single ring graduation mark and a label. The label should show the nominal volume, tolerance, calibration temperature, class, relevant manufacturing standard and the manufacturer’s logo. The glass or plastic is generally clear but may be amber colored for handling light sensitive compounds such as silver nitrate or vitamin A.
They both do something :)
You would use a graduated cylinder or a volumetric flask to measure 1cm3 of alcohol accurately. These tools are designed to measure precise volumes of liquid.
The best instrument to use to prepare a solution depends on the accuracy and volume of the solution needed. Common instruments include pipettes for precise measurements and volumetric flasks for accurate volume measurements. Additionally, a balance may be used to weigh out solid solutes for solution preparation.
The volumetric flask is the best.
Graduated cylinders that are kind of red Volumetric Flask
It can but it's no use because in a volumetric flask are desired to obtain a pure solution with a well known concentration.

As the pipette is far more accurate than a flask by a factor 10 to 100 one should NOT use a volumetric flask except for standard volumes over 100 ml.
Volumetric flasks are designed to hold specific volumes of liquid accurately for dilution or mixing purposes. Storing solutions in a volumetric flask can lead to evaporation, contamination, and inaccuracies in concentration due to the narrow neck of the flask making it difficult to access the solution for further use. It is best to store solutions in appropriate containers designed for long-term storage.

Well, look there. The image associated with your question actually SHOWS the answer.Erlenmeyer flasks are generally marked in units of mL. These should be taken as approximations at best; if you need an accurate amount, use a volumetric flask.

AnswerA flask is a container for storing or carrying liquid.It also keeps the liquid at the same temparature over a number of hours. A flask is nominally used for carrying liquids in it and usually of the alcoholic nature, and is usually referred to as a hip flask as it is carried in a pocket either the front or back.
