Answer:

Glassware used to accurately transfer small volumes → A

Glassware used to accurately transfer a small, single volume → B

Glassware used to deliver a volume not known in advance → D

Glassware best used when greater access to the contents is needed → C

Glassware used to prevent splashing or evaporation → E            

Glassware used to make accurate solutions → F    

Explanation:

A) A graduated pipette is used to accurately transfer volumes because it has graduated marks that increase along the tube. It permits the transfer of a small volume of liquids.      

B) A volumetric pipette is used to accurately transfer a single volume of liquid because it has a large bulb with a single graduation mark that is calibrated for a single volume.          

C) A beaker is used to prepare solutions, to perform crystallization, to transfer and hold solutions, decanting liquids and other more. Its large opening permits greater access to the contents. Even when Beakers are often graduated they can not be used to measure accurate volumes of liquid.                

D) A burette is used for accurately dispensing variable known volumes of liquid, especially in titrations, which is an volumetric analysis in where the amount of volume about to be used to reach the endpoint is unknown yet.

E) Erlenmeyer flask is used to mix solutions by swirling without the risk of spillage because of its narrow neck. This narrow neck also permits the prevention of rapid evaporation of the liquids.    

F) A volumetric flask can be used to prepare accurate solutions since it is designed to a specific volume of liquid and therefore the solutions prepared in it will have an accurately known concentration.  

Therefore, the answer to the statements are the following:

Glassware used to accurately transfer small volumes → A

Glassware used to accurately transfer a small, single volume → B

Glassware used to deliver a volume not known in advance → D

Glassware best used when greater access to the contents is needed → C

Glassware used to prevent splashing or evaporation → E            

Glassware used to make accurate solutions → F    

I hope it helps you!

An experiment can be defined as a systematic investigation carried out under controlled conditions, in order for a scientist to manipulate an independent variable (the cause) while determining and measuring the dependent variable (the effect) through series of observation.

During an experiment, some examples of the apparatus used in the laboratory and their functions are:

  • Graduated pipette: it is a glassware which is used to accurately transfer small volumes of a liquid.

  • Volumetric Pipette: it is a glassware which is used to accurately transfer a small, single volume of a liquid.

  • Burette: it is a glassware which is used to deliver a volume of a liquid that isn't known in advance.

  • Beaker: it is a glassware which is best used when greater access to the contents is needed.

  • Erlenmeyer flask: it is a glassware which is used to prevent splashing or evaporation.

  • Volumetric Flask: it is a glassware which is used to make accurate solutions of a solvent and solute.

Note: A glassware refers to any object that is made up of glass.
