Lab Equipment Quiz

What is the main purpose of a beaker in a laboratory?

• To measure weight of substances

• To hold and measure liquids

• To heat substances

• To store solid chemicals

How is a beaker different from a graduated cylinder?

• A beaker is used for measuring the volume of liquids, while a graduated cylinder is used for heating liquids.

• A beaker has a wide mouth and is used for stirring, mixing, and heating liquids, while a graduated cylinder is used for measuring the volume of liquids more accurately.

• A beaker is used for measuring temperature, while a graduated cylinder is used for mixing chemicals.

• A beaker is made of plastic, while a graduated cylinder is made of glass.

What are the common sizes of beakers used in a laboratory?

• 200 mL, 300 mL, 400 mL, 600 mL, 700 mL

• 10 mL, 20 mL, 30 mL, 40 mL, 60 mL

• 50 mL, 100 mL, 250 mL, 500 mL, 1000 mL

• 1 L, 2 L, 3 L, 4 L, 5 L

What is the function of a graduated cylinder?

• Measuring the volume of liquids.

• Measuring the weight of solids

• Storing chemicals safely

• Heating up substances

How is a graduated cylinder used to measure liquid volume?

• By dipping a finger into the liquid and estimating the volume based on the depth of the wet finger.

• By holding the cylinder up to the light and guessing the volume based on the shadow it casts.

• By pouring the liquid into the cylinder and reading the measurement at the bottom of the meniscus.

• By shaking the cylinder and estimating the volume based on the sound it makes.

What are the units of measurement typically found on a graduated cylinder?

• milliliters (mL) or cubic centimeters (cm^3)

• grams

• inches

• liters

What is the primary use of a test tube in a laboratory?

• Measuring precise volumes of gases

• Storing large quantities of liquids

• Mixing substances in large beakers

• Holding, mixing, or heating small quantities of substances

How is a test tube different from a beaker?

• A test tube is wider at the top, while a beaker is wider at the bottom.

• A test tube is narrow and used for small quantities, while a beaker is cylindrical and used for larger quantities.

• A test tube is made of plastic, while a beaker is made of glass.

• A test tube is used for mixing chemicals, while a beaker is used for heating chemicals.

What are the different types of test tubes commonly used in a laboratory?

• Pipette, burette, and condenser

• Culture tubes, centrifuge tubes, and boiling tubes

• Erlenmeyer flask, test tube, and graduated cylinder

• Beaker, flask, and petri dish

What is the function of a pipette in a laboratory?

• Stirring liquids in a beaker

• Accurately measure and transfer small volumes of liquid

• Weighing solid chemicals

• Measuring temperature of a solution
