For measuring and heating a chemical in an experiment using a graduated cylinder, the most suitable option would be: B. Glass cylinder

Glass graduated cylinders are commonly used in laboratory settings for measuring and mixing liquids, as they offer several advantages:

  1. Heat Resistance: Glass cylinders can withstand moderate levels of heat, making them suitable for heating substances directly over a Bunsen burner or hot plate if necessary. They have good thermal resistance compared to plastic cylinders, which might melt or deform when exposed to high temperatures.
  2. Chemical Resistance: Glass cylinders are generally resistant to a wide range of chemicals and solvents, ensuring that they won't react with the substances being measured or heated, which could affect the accuracy of the experiment or pose safety hazards.
  3. Durability and Accuracy: Glass cylinders are durable and less prone to scratches, ensuring their accuracy and precision in measurements over time. They provide clear visibility, allowing for accurate readings due to their transparency.

While plastic graduated cylinders might also be available, they have limitations in terms of heat resistance, chemical compatibility, and durability compared to glass cylinders. Metal cylinders are less common for measuring liquids in a laboratory setting due to their opaque nature and potential reactivity with certain substances.

Therefore, when considering the need to measure and heat a chemical for an experiment, a glass graduated cylinder is the most suitable choice.
