• Mortar and Pestle

• Graduated Cylinder

What is the function of a table beam?

• Heating liquids

• Identifying acids and bases

• Measuring mass

• Observing cells

A digital microscope is primarily used to:

• Identify acids and bases

• Measure liquid volume

• Observe cell structures

• Heat liquids

Which laboratory tool is used to grind materials in a chromatography experiment?

• Telescope

• Test Tubes

• Beaker

• Mortar and Pestle

What is the purpose of a telescope?

Which tool is used to hold liquids and has a spout for pouring?

• Erlenmeyer Flask

• Beaker

• Graduated Cylinder

• Test Tubes

Mass is defined as:

• The ability of matter to hold liquid

• The amount of space occupied by matter

• The ability of a material to reflect light

• The amount of matter present in an object

What is the formula for volume?
