C
Graduated cylinder
D
Bunsen burner
Verified step by step guidance1
Understand that the question asks for the laboratory equipment used to measure the volume of a liquid accurately.
Recall the common laboratory glassware and their primary uses: a beaker is mainly for holding and mixing liquids, an Erlenmeyer flask is used for mixing and heating, a Bunsen burner is for heating substances, and a graduated cylinder is specifically designed for measuring liquid volumes.
Recognize that accuracy in volume measurement requires equipment with precise volume markings and a narrow shape to reduce reading errors.
Identify that the graduated cylinder has clear, graduated markings along its length, allowing for more precise volume readings compared to beakers or flasks.
Conclude that the graduated cylinder is the most appropriate and commonly used piece of equipment for accurately measuring the volume of a liquid.
