Correct Answer
B. ThermometerExplanation
A thermometer is an instrument used to measure temperature. It typically consists of a glass tube filled with a liquid, such as mercury, that expands or contracts with temperature changes. By observing the level of the liquid, the temperature can be determined. The other options, such as test tube brush, dropper, and test tube holder, are not used for temperature measurement but for other laboratory purposes.Rate this question:

B. SlidesExplanation
Slides are thin, flat, rectangular pieces of glass or plastic that are used to hold specimens for observation under a microscope. They provide a smooth and transparent surface for the specimen to be placed on, allowing light to pass through and enabling clear visualization. In contrast, coverslips are smaller pieces of glass or plastic that are used to cover the specimen on the slide, protecting it and preventing contamination. A microscope is an instrument used for magnifying and examining specimens, and a beaker is a cylindrical glass or plastic container used for holding and mixing liquids and chemicals in a laboratory setting.Rate this question:

Which of the following pieces of laboratory equipment is used to accurately measure and deliver variable volumes of liquid?
- A.
Graduated cylinder
- B.
Volumetric flask
- C.
Burette
- D.
Pipette
Correct Answer
C. BuretteExplanation
A burette is a long, graduated glass tube with a stopcock at the bottom, allowing for precise control and delivery of variable liquid volumes. While graduated cylinders and pipettes also measure liquids, they are less precise for delivering specific, varying amounts. Volumetric flasks are designed to hold a single, precise volume, not for dispensing variable amounts.Rate this question:

What is the primary function of a desiccator in a laboratory setting?
- A.
To sterilize glassware and equipment.
- B.
To store volatile chemicals safely.
- C.
To create a dry environment for storing moisture-sensitive substances.
- D.
To culture microorganisms under controlled conditions.
Correct Answer
C. To create a dry environment for storing moisture-sensitive substances.Explanation
A desiccator is a sealed container that maintains a low-humidity environment using a desiccant material (like silica gel) to absorb moisture. This protects hygroscopic substances, which readily absorb moisture from the air, from degradation or alteration. It's not used for sterilization, storing volatile chemicals, or culturing microorganisms.Rate this question:

Which of the following laboratory techniques is used to separate a solid precipitate from a liquid solution?
- A.
Titration
- B.
Distillation
- C.
Centrifugation
- D.
Spectrophotometry
Correct Answer
C. CentrifugationExplanation
Centrifugation uses centrifugal force to separate substances of different densities. When a mixture of solid and liquid is spun rapidly in a centrifuge, the denser solid particles settle at the bottom, allowing for separation from the liquid. Titration is used for chemical analysis, distillation separates liquids based on boiling points, and spectrophotometry measures light absorption or transmission.Rate this question:
